ARI's Gaia TAP Service

ARI's Gaia TAP Service ARI-Gaia ivo://uni-heidelberg.de/gaia/tap Astronomisches Rechen-Institut Jon juaristi Campillo juaristi@uni-heidelberg.de Gaia This service provides Gaia data (currently DR1, DR2, EDR3 and DR3), with full-sky catalogues of high-precision positions down to about 20 mag, as a mirror of the original ESA archive with extra features (e.g., tables and column metadata). https://gaia.ari.uni-heidelberg.de Catalog Research https://gaia.ari.uni-heidelberg.de/tap ObsCore-1.1 ADQL 2.0 ADQL 2.0 Returns the index of the (nest) Healpix cell (at the specified order: hpxOrder) containing the specified spherical point (ra, dec). Returns the index of the (nest) Healpix cell (at the specified order: hpxOrder) containing the specified spherical point. Returns a POINT corresponding to the center of the Healpix cell with the given index at the given order. Returns the index of the (nest) Healpix cell (at the specified order: hpxOrder) containing the specified Gaia source. The Healpix index is actually extracted from the given Gaia source_id. Returns a POINT for a given position (ra and dec) with a given proper motion (pmra and pmdec) after a given number of Julian years. Positions must be in degrees, proper motions are expected in degrees/year). pmra is assumed to contain cos(delta). NOTE: This currently is a crappy approximation that does *not* go through the tangential plane. If you use it, let the operators know so we replace it with something real. NOTE 2: This function is a clone of the function ivo_apply_pm provided by GAVO's TAP service. The aggregate function returns a histogram of val with nbins+2 elements. Assuming 0-based arrays, result[0] contains the number of underflows (i.e., val<lower), result[nbins+1] the number of overflows. Elements 1..nbins are the counts in nbins bins of width (upper-lower)/nbins. Clients will have to convert back to physical units using some external communication, there currently is no (meta-) data as lower and upper in the TAP response. Returns an array column in a per-row basis. When it is used for multiple columns, each row will contain a[0], b[0], but be aware that lengths my differ. Returns the greatest value between the two Returns the lowest value between the two Returns the average value of the array Returns the maximum value of the array Returns the min value of the array Returns the standard deviation of the array Returns the square root of the array application/x-votable+xml votable application/x-votable+xml;serialization=BINARY2 votable/b2 application/x-votable+xml;serialization=TABLEDATA votable/td application/x-votable+xml;serialization=FITS votable/fits application/fits fits application/json json text/csv csv text/tab-separated-values tsv text/plain text text/html html 259200 604800 1800 14400 100000 10000000 10000000 10000000 https://gaia.ari.uni-heidelberg.de/tap/tables https://gaia.ari.uni-heidelberg.de/tap/capabilities https://gaia.ari.uni-heidelberg.de/tap/examples https://gaia.ari.uni-heidelberg.de/tap/availability gaiafpr gaiafpr.crowded_field_source526587Sources based on Service Interface Function (SIF) images of very dense regions in the sky.

gaiadr3.dr2_neighbourhoodUsers wishing to look up the E/DR3 record for an astrophysical source identified in DR2 must NOT simply extract the record from E/DR3 having the same source identifier. As described in the detailed description of attribute designation in GaiaSource it is not guaranteed that the same astronomical source will always have the same source identifier in different Data Releases. Hence the only safe way to compare source records between different Data Releases in general is to check the records of proximal source(s) in the same small part of the sky. This table provides the means to do this via a precomputed crossmatch of such sources, taking into account the proper motions available at E/DR3. Within the neighbourhood of a given E/DR3 source there may be none, one or (rarely) several possible counterparts in DR2 indicated by rows in this table. This occasional source confusion is an inevitable consequence of the merging, splitting and deletion of identifiers introduced in previous releases during the DR3 processing and results in no guaranteed one–to–one correspondence in source identifiers between the releases. For more details of the procedure used to create this crossmatch, see Chapter [chap:archive] in the online documentation.2113601284 dr3_source_id Source identifier in Gaia E/DR3 meta.id.cross;meta.main BIGINT indexed primary dr2_source_id Source identifier in Gaia DR2 meta.id.cross BIGINT indexed primary angular_distance Angular distance between the two sources mas pos.angDistance REAL indexed magnitude_difference G band magnitude difference between the sources mag phot.mag;arith.diff REAL indexed proper_motion_propagation Flag indicating whether E/DR3 coordinates were proper motion corrected meta.code.status SMALLINT

gaiadr3.frame_rotator_sourceSources used to compute the Gaia reference frame.The AGIS frame rotator algorithm has two different parts: the reference frame orientation; and the reference frame spin. The reference frame orientation is fixed using the International Earth Rotation and Reference System Service (=IERS) position of a subset of IERS sources defining the third realization of the International Coordinate Reference Frame , http://hpiers.obspm.fr/icrs-pc/newwww/icrf/index.php. The reference frame spin is defined using the Gaia proper motion of a list of QSOs. The reference frame algorithms have an outliers scheme. Hence for each aspect we provide the considered sources and the used sources actually used, and the number of used sources might be lower than the number of considered sources.429249 source_id Gaia source identifier meta.id;meta.main BIGINT indexed considered_for_reference_frame_orientation Considered for the reference frame orientation meta.version SMALLINT considered_for_reference_frame_spin Considered for the reference frame spin meta.version SMALLINT used_for_reference_frame_orientation Used for the reference frame orientation meta.version SMALLINT used_for_reference_frame_spin Used for the reference frame spin meta.version SMALLINT

The best neighbour is chosen among good neighbours as the one with the highest value of the figure of merit, which evaluates the ratio between two opposite models/hypotheses: the counterpart candidate is a match or it is found by chance. Good neighbours are nearby objects in the external catalogue whose position is compatible within position errors with the Gaia target. The cross-match algorithm is positional and exploits the full 5 parameters covariance matrix of Gaia astrometric solution when available and the external catalogue positions and position errors. In addition it takes into account the external catalogue environment using the local density.469051627 source_id Unique Gaia source identifier meta.id;meta.main BIGINT indexed clean_tmass_psc_xsc_oid External Catalogue source identifier meta.id.cross INTEGER original_ext_source_id Original External Catalogue source identifier meta.id.cross VARCHAR indexed angular_distance Angular Distance between the two sources arcsec pos.angDistance REAL indexed number_of_neighbours Number of neighbours in External Catalogue meta.version SMALLINT number_of_mates Number of mates in Gaia Catalogue meta.version SMALLINT xm_flag Cross-match algorithm flag meta.code.status SMALLINT

gaiadr3.tmass_psc_xsc_neighbourhood2MASS Neighbourhood table includes all good neighbours for each matched Gaia object. A good neighbour for a given Gaia source is a nearby object in the external catalogue whose position is compatible (within position errors) with the Gaia target. The cross-match algorithm is not symmetric and searches Gaia sources counterparts in 2MASS.

gaiadr3.tmass_psc_xsc_joinConvenience table to be used to join 2MASS PSC+XSC catalogue with the cross-match results. The table links the external catalogue original source_id (original_ext_source_id) to the corresponding the additional numerical identifier (clean_tmass_psc_xsc_oid). Both original_ext_source_id and clean_tmass_psc_xsc_oid are present in the cross-match output tables (tmassPscXscBestNeighbour and tmassPscXscNeighbourhood). However, in case there are suspected duplicates in the external catalogue, different original_ext_source_id will correspond to the same clean_tmass_psc_xsc_oid.In the cross-match output table only the original_ext_source_id of the source with the best astrometry among the suspected duplicates will be listed. In practice, users may use the original_ext_source_id in the original catalogue to find the matching source with the best astrometry. Users interested to find all matching suspected duplicates should instead use the clean_tmass_psc_xsc_oid in the join with the cross-match result tables.471063502 clean_tmass_psc_xsc_oid External Catalogue source identifier meta.id.cross INTEGER indexed original_psc_source_id Original 2MASS PSC source identifier meta.version VARCHAR indexed original_xsc_source_id Original 2MASS XSC source identifier meta.version VARCHAR indexed

gaiadr3.tycho2tdsc_mergeTycho-2 merged with the TDSC catalog and TDSC supplement. The Tycho Double Star Catalogue, (TDSC, ) contains 98482 components of double and multiple systems processed in the Tycho-2 context. It includes either original Tycho-2 data or results from a dedicated re-processing aimed at binaries. As pointed out by P. Marrese (personal communication), the TDSC star with identifier 29583 is redundant and it was therefore skipped. The TDSC supplement contains data from an additional 4777 components from either Hipparcos or Tycho-1. The Tycho-2 main catalogue contains 2539913 sources, including many binaries, but a minimum separation of 0.8 arcsec was imposed during the catalogue construction. The Tycho-2 supplement-1 contains data for 17588 Hipparcos and Tycho-1 stars, which do not appear in the main catalogue, but only the 4777 stars relevant for TDSC are included here. The Tycho-2 supplement-2 contains an additional 1146 Tycho-1 stars of poor quality. We have merged Tycho-2 (main) with the TDSC main and supplement, keeping the Tycho-2 data model and extending it to include TDSC–specific fields. This is only possible to a certain degree as specified in detail below. In particular, Tycho-2 includes fields for mean position, proper motion etc. for a combination of Tycho-2 and several ground based catalogues. These fields are inherited for TDSC main stars, but were not derived for the TDSC supplement, where we only provide HIP proper motions. For Tycho-2 stars not in TDSC, blank TDSC fields were appended. For Tycho-2 stars in TDSC, the following fields were replaced by the corresponding TDSC fields: - tyc1, tyc2, tyc3; - hip; - ccdm. In addition, if the TDSC contains a new solution: - btMag, eBtMag, vtMag, eVtMag, raDeg, deDeg, epRa1990, epDe1990, eRaDeg, eDeDec; - The mean position flag, pflag, is set to ‘P’ (“photocentre") if resolved and there are Tycho-2 mean positions. Mean position etc. are then repeated for both new components; - The proximity indicator, prox, is set to blank if the Tycho-2 star was resolved in TDSC; - The type-of-solution flag, posflg, set to ‘N’; - For resolved Tycho-2 stars, two records are given. For the few TDSC stars with new solutions, but not in Tycho-2, and for the TDSC supplement stars (Hipparcos or Tycho-1), the Tycho-2 part of the merged record was populated in the following way: - TYC1..3 from TDSC; - pflag set to TDSC pmflg (‘H’ or ‘X’), ‘H’ indicating Hip proper motions; - no mean position and related fields; - proper motions only for Hipparcos stars; - $B_{\rm T}, V_{\rm T}$ photometry from TDSC; - Tycho-1 flag, tyc, is set to posflg, i.e. ‘T’ or ‘H’ although Hipparcos stars may well be in Tycho-1; - Hipparcos, hip, and CCDM, ccdm, identifiers from TDSC; - astrometry from TDSC, but the (ra, dec)-correlation, corr, is set to blank. New TDSC specific fields added after the Tycho-2 part of the record: - sysNo, cmp, nMain, nSup, magflg, wds, note, hd; - rcmp, pa, sep, ePa, ePaSep, eSep.2561887 id Tycho-2 identifier meta.id;meta.main VARCHAR primary hip Hipparcos number meta.id.cross INTEGER primary tyc1 TYC1 component from TYC or GSC meta.id.part;meta.main VARCHAR indexed primary tyc2 TYC2 component from TYC or GSC meta.id.part;meta.main VARCHAR indexed primary tyc3 TYC3 component from TYC or TDSC meta.id.part;meta.main VARCHAR indexed primary id_tycho Numeric Tycho-2 identifier meta.id;meta.dataset BIGINT primary tyc Tycho-1 star meta.code VARCHAR primary ra Observed Tycho-2 Right Ascension, ICRS deg pos.eq.ra DOUBLE indexed primary dec Proper motion in RA*cos(dec) deg pos.eq.dec DOUBLE indexed primary pm_ra Proper motion in RA*cos(dec) mas/yr pos.eq.ra;pos.pm REAL indexed primary pm_de Proper motion in Dec mas/yr pos.eq.dec;pos.pm REAL indexed primary corr Correlation (RAdeg,DEdeg) stat.correlation;pos.eq.ra;pos.eq.dec DOUBLE indexed primary bt_mag Tycho-2 BT magnitude mag phot.mag;em.opt.B REAL indexed ccdm CCDM component identifier for HIP stars meta.code.multip VARCHAR cmp Component designation meta.id.part VARCHAR de_deg Observed Tycho-2 Declination, ICRS deg pos.eq.dec DOUBLE de_mdeg Mean Declination, ICRS, at epoch=J2000 deg pos.eq.dec DOUBLE e_bt_mag Uncertainty of BT mag stat.error REAL e_de_deg Uncertainty of observed Tycho-2 Dec. mas stat.error DOUBLE e_de_mdeg Uncertainty of Dec at mean epoch. mas stat.error DOUBLE e_pa Uncertainty of the position angle deg stat.error REAL e_pa_sep Uncertainty of the position angle * separation stat.error SMALLINT ep_de1990 Epoch--1990 of deDeg yr time.epoch REAL ep_de_m Mean epoch of Dec. yr time.epoch REAL e_pm_de Uncertainty of proper motion in Dec. mas/yr stat.error REAL e_pm_ra Uncertainty proper motion in RA*cos(dec). mas/yr stat.error REAL ep_ra1990 Epoch--1990 of raDeg yr time.epoch REAL ep_ra_m Mean epoch of RA. yr time.epoch REAL e_ra_deg Uncertainty RA*cos(dec), of observed Tycho-2 RA. mas stat.error DOUBLE e_ra_mdeg Uncertainty RA*cos(dec),at mean epoch. mas stat.error DOUBLE e_sep Uncertainty of the separation mas stat.error SMALLINT e_vt_mag Uncertainty of VT mag stat.error REAL hd HD identifier for TDSC entries meta.id.cross INTEGER magflg TDSC photometry flag meta.code CHAR n_main Number of components in TDSC main catalogue meta.number SMALLINT note TDSC notes meta.note CHAR n_sup Number of components in the TDSC supplement meta.number SMALLINT num Number of positions used for forming mean data meta.number SMALLINT pa Position angle deg pos.posAng REAL pflag Mean position flag meta.code VARCHAR posflg Type of Tycho-2 solution meta.id;stat.fit VARCHAR prox Proximity indicator 100mas meta.code SMALLINT q_de_mdeg Goodness of fit for mean Dec meta.code.qual REAL q_pm_de Goodness of fit for pmDe meta.code.qual REAL q_pm_ra Goodness of fit for pmRa meta.code.qual REAL q_ra_mdeg Goodness of fit for mean RA meta.code.qual REAL ra_deg Observed Tycho-2 Right Ascension, ICRS deg pos.eq.ra DOUBLE ra_mdeg Mean Right Ascension, ICRS, epoch=J2000 deg pos.eq.ra DOUBLE rcmp Reference component for position angle and separation meta.id.assoc VARCHAR sep Separation arcsec pos.angDistance REAL sys_no TDSC identifier for the system meta.id INTEGER vt_mag Tycho-2 VT magnitude mag phot.mag;em.opt.V REAL indexed wds WDS identifier for the system meta.id.cross VARCHAR

gaiaedr3.dr2_neighbourhoodUsers wishing to look up the E/DR3 record for an astrophysical source identified in DR2 must NOT simply extract the record from E/DR3 having the same source identifier. As described in the detailed description of attribute designation in GaiaSource it is not guaranteed that the same astronomical source will always have the same source identifier in different Data Releases. Hence the only safe way to compare source records between different Data Releases in general is to check the records of proximal source(s) in the same small part of the sky. This table provides the means to do this via a precomputed crossmatch of such sources, taking into account the proper motions available at E/DR3. Within the neighbourhood of a given E/DR3 source there may be none, one or (rarely) several possible counterparts in DR2 indicated by rows in this table. This occasional source confusion is an inevitable consequence of the merging, splitting and deletion of identifiers introduced in previous releases during the DR3 processing and results in no guaranteed one–to–one correspondence in source identifiers between the releases. For more details of the procedure used to create this crossmatch, see Chapter [chap:archive] in the online documentation.2113601284 dr3_source_id Source identifier in Gaia E/DR3 meta.id.cross;meta.main BIGINT indexed primary dr2_source_id Source identifier in Gaia DR2 meta.id.cross BIGINT indexed primary angular_distance Angular distance between the two sources mas pos.angDistance REAL indexed magnitude_difference G band magnitude difference between the sources mag phot.mag;arith.diff REAL indexed proper_motion_propagation Flag indicating whether E/DR3 coordinates were proper motion corrected meta.code.status SMALLINT

gaiaedr3.commanded_scan_lawThis table provides a representation of the Gaia scanning law over the 34 month time period covered by the Gaia Data Release 3 (from 2014-07-25 10:31:26 to 2017-05-28 08:46:29), including the Ecliptic Pole Scanning at the begin of the mission. Note that this is the commanded attitude of the spacecraft, the actual attitude could deviate from it by up to about 30 arcsec. Also, it does not contain any of the data interruptions that occurred during the real mission, of which the main ones are listed in Chapter [chap:cu0int], Section [cu0int_sec:release_framework]. The scanning law has been sampled at a 10 second interval, in which the satellite rotates about 10 arcminutes (the target spin rate is actually 59.9641857803 arcsec/sec). Note that this is several times shorter than a typical field-of-view transit and the scan position angle will be practically constant during this interval. Notes: - The times in columns 1, 2 and 3 are in Julian days in TCB with time origin 2010-01-01T00:00 (JD 2455197.5), following the time coordinate convention used in the Gaia archive. TCB stands for Barycentric Coordinate Time and is the time standard used in Gaia processing, equivalent to the proper time experienced by a clock at rest in a coordinate frame co-moving with the barycentre of the Solar system but outside its gravity well, therefore not influenced by the gravitational time dilation caused by the Sun and the rest of the solar system. - Column 1 is the reference time for the spacecraft attitude, while columns 2 and 3 give the times with the (relativistic) corrections applied for the light-travel time to the solar system barycentre, corresponding to an infinitely distant source at the RA, DEC at the centres of FOV 1 and 2, respectively. - FOV1 and FOV2 correspond to the preceding (PFOV) and following (FFOV) fields-of-view, respectively. - The centres of the field of views are separated by the basic angle of 106.5 deg, see Fig. 2 of . Their origin in the focal plane is illustrated in Fig. 3 of the same paper: both originate in the astrometric field (AF) 7, with FOV1 in row 3 and FOV2 in row 5. - The scan angle, theta, is the position angle of the direction in which the FOV is moving (also called ‘along-scan’ direction), and is defined in the usual astronomical sense: theta = 0 when the FoV is moving towards local North, and theta = 90 degrees towards local East. - All values have been formatted to the default double numerical precision and so this precision should not be interpreted as the accuracy of the data.8967691 ra_fov1 Right Ascension of FOV1 centre deg meta.version REAL primary dec_fov1 Declination of FOV1 centre deg meta.version REAL primary bjd_fov1 Time [Julian Date in TCB at barycentre for FOV1 - 2455197.5] Barycentric JD in TCB - 2455197.5 (day) meta.version DOUBLE primary scan_angle_fov1 Scan position angle of FOV1 deg meta.version REAL primary ra_fov2 Right ascension of FOV2 centre deg meta.version REAL primary dec_fov2 Declination of FOV2 centre deg meta.version REAL primary bjd_fov2 Time [Julian Date in TCB at barycentre for FOV2 - 2455197.5] Barycentric JD in TCB - 2455197.5 (day) meta.version DOUBLE primary scan_angle_fov2 Scan position angle of FOV2 deg meta.version REAL primary jd_time Time [Julian Date in TCB at Gaia - 2455197.5] Julian Date (day) meta.version DOUBLE indexed primary heal_pix_fov1 FOV1 HEALPix level 12 meta.version INTEGER primary heal_pix_fov2 FOV2 HEALPix level 12 meta.version INTEGER primary obmt_time Time at Gaia (OBMT) OBMT meta.version BIGINT primary solution_id Solution Identifier meta.version BIGINT indexed primary

gaiaedr3.frame_rotator_sourceSources used to compute the Gaia reference frame. The AGIS frame rotator algorithm has two different parts: the reference frame orientation; and the reference frame spin. The reference frame orientation is fixed using the International Earth Rotation and Reference System Service (=IERS) position of a subset of IERS sources defining the third realization of the International Coordinate Reference Frame (Charlot et al., 2020, submitted to A&A), http://hpiers.obspm.fr/icrs-pc/newwww/icrf/index.php. The reference frame spin is defined using the Gaia proper motion of a list of QSOs. The reference frame algorithms have an outliers scheme. Hence for each aspect we provide the considered sources and the used sources actually used, and the number of used sources might be lower than the number of considered sources.429249 source_id Gaia source identifier meta.id.cross BIGINT indexed primary considered_for_reference_frame_orientation considered for the reference frame orientation meta.code SMALLINT primary considered_for_reference_frame_spin considered for the reference frame spin meta.code SMALLINT primary used_for_reference_frame_orientation used for the reference frame orientation meta.code.status SMALLINT primary used_for_reference_frame_spin used for the reference frame spin meta.code.status SMALLINT primary

gaiaedr3.allwise_best_neighbourLists each matched Gaia object with its best neighbour in the external catalogue. The cross-match algorithm is not symmetric and searches Gaia source counterparts in AllWISE. The best neighbour is chosen among good neighbours as the one with the highest value of the figure of merit, which evaluates the ratio between two opposite models/hypotheses: the counterpart candidate is a match or it is found by chance. Good neighbours are nearby objects in the external catalogue whose position is compatible within position errors with the Gaia target. The cross-match algorithm is positional and exploits the full 5 parameter covariance matrix from the Gaia astrometric solution when available and the external catalogue positions and position errors.

gaiaedr3.tycho2tdsc_mergeTycho-2 merged with the TDSC catalog and TDSC supplement. The Tycho Double Star Catalogue, (TDSC, ) contains 98482 components of double and multiple systems processed in the Tycho-2 context. It includes either original Tycho-2 data or results from a dedicated re-processing aimed at binaries. As pointed out by P. Marrese (personal communication), the TDSC star with identifier 29583 is redundant and it was therefore skipped. The TDSC supplement contains data from an additional 4777 components from either Hipparcos or Tycho-1. The Tycho-2 main catalogue contains 2539913 sources, including many binaries, but a minimum separation of 0.8 arcsec was imposed during the catalogue construction. The Tycho-2 supplement-1 contains data for 17588 Hipparcos and Tycho-1 stars, which do not appear in the main catalogue, but only the 4777 stars relevant for TDSC are included here. The Tycho-2 supplement-2 contains an additional 1146 Tycho-1 stars of poor quality. We have merged Tycho-2 (main) with the TDSC main and supplement, keeping the Tycho-2 data model and extending it to include TDSC–specific fields. This is only possible to a certain degree as specified in detail below. In particular, Tycho-2 includes fields for mean position, proper motion etc. for a combination of Tycho-2 and several ground based catalogues. These fields are inherited for TDSC main stars, but were not derived for the TDSC supplement, where we only provide HIP proper motions. For Tycho-2 stars not in TDSC, blank TDSC fields were appended. For Tycho-2 stars in TDSC, the following fields were replaced by the corresponding TDSC fields: - tyc1, tyc2, tyc3; - hip; - ccdm. In addition, if the TDSC contains a new solution: - btMag, eBtMag, vtMag, eVtMag, raDeg, deDeg, epRa1990, epDe1990, eRaDeg, eDeDec; - The mean position flag, pflag, is set to ‘P’ (“photocentre") if resolved and there are Tycho-2 mean positions.

gaiaedr3_complements Datasets derived from Gaia-EDR3. These tables are published by ARI/ZAH but are NOT official Gaia/DPAC products. gaiaedr3_complements.distancesGeometric and photogeometric distances to 1.47 billion stars in Gaia Early Data Release 3 (eDR3) C.A.L. Bailer-Jones et al. (MPIA Heidelberg, calj@mpia.de) December 2020 The catalogue provides distance estimates from the Sun to sources in Gaia EDR3 that have parallaxes. Two types of distance estimates are provided, together with their corresponding asymmetric uncertainties, using Bayesian posterior density functions that sampled for each source. The prior is based on a detailed model of the 3D spatial, colour, and magnitude distribution of stars in our Galaxy that includes a 3D map of interstellar extinction. The first type of distance estimate is purely geometric, in that it only makes use of the Gaia parallax and parallax uncertainty. This uses a direction-dependent distance prior derived from the Galaxy model. The second type of distance estimate is photogeometric: in addition to parallax it also uses the source's G-band magnitude and BP-RP colour. This type of estimate uses the geometric prior together with a direction-dependent and colour-dependent prior on the absolute magnitude of the star. The distance estimate and uncertainties are quantiles, so are invariant under logarithmic transformations. This means that the median estimate of the distance can be used to give the median estimate of the distance modulus, and likewise for the uncertainties. The catalogue comprises one table with 1.47 billion rows and eight columns.1467744818 source_id Gaia source identifier, identical to the Gaia-EDR3 source_id (cannot be matched against DR1 or DR2 source ID). meta.id;meta.main BIGINT indexed primary r_med_geo Median of the geometric distance posterior.

gaiadr2.dr1_neighbourhoodUsers wishing to look up the DR2 record for an astrophysical source identified in DR1 must NOT simply extract the record from DR2 having the same source identifier. As described in the detailed description of attribute designation in GaiaSource it is not guaranteed that the same astronomical source will always have the same source identifier in different Data Releases. Hence the only safe way to compare source records between different Data Releases in general is to check the records of proximal source(s) in the same small part of the sky. This table provides the means to do this via a precomputed crossmatch of such sources, taking into account the proper motions available at DR2. Within the neighbourhood of a given DR2 source there may be none, one or (rarely) several possible counterparts in DR1 indicated by rows in this table. This occasional source confusion was introduced during the DR1 processing which used an earlier version of the software for matching of transit observations to unique astrophysical sources. The subsequent merging, splitting and deletion of identifiers introduced at DR1 during the DR2 processing means there is no guaranteed one–to–one correspondence in source identifiers between the releases. For more details of the procedure used to create this crossmatch, see Section [chap:xmdr1] in the online documentation.1141288704 angular_distance Angular distance between the two sources arcsec pos.angDistance REAL indexed dr1_source_id Source identifier in Gaia DR1 meta.id.cross BIGINT indexed primary dr2_source_id Source identifier in Gaia DR2 meta.id.cross;meta.main BIGINT indexed primary magnitude_difference G band magnitude difference between the sources mag phot.mag;arith.diff REAL indexed rank Rank metric indicating relative probability of a good match stat.probability REAL

gaiadr2.ruweThis table contains the Renormalised Unit Weight Error (RUWE) associated to each source in gaia_source. The RUWE is expected to be around 1.0 for sources where the single-star model provides a good fit to the astrometric observations. A value significantly greater than 1.0 (say, >1.4) could indicate that the source is non-single or otherwise problematic for the astrometric solution. The desciption of how this parameter is calculated is described in the document ”Re-normalising the astrometric chi-square in Gaia DR2”, which can be downloaded from: https://www.cosmos.esa.int/web/gaia/public-dpac-documents1692918784 ruwe Renormalised unit weight error stat.error REAL indexed source_id Unique source identifier (unique within a particular Data Release) meta.id BIGINT indexed

These tables are published by ARI/ZAH but are NOT official Gaia/DPAC products. gaiadr2_complements.geometric_distanceEstimating distances from parallaxes IV: Distances to 1.33 billion stars in Gaia data release 2 C.A.L. Bailer-Jones et al. (MPIA Heidelberg, calj@mpia.de) April 2018 The catalogue provides distances estimates (and uncertainties therein) for 1.33 billion stars over the whole sky brighter than about G=20.7. These have been estimated using the parallaxes (and their uncertainties) from Gaia data release 2. A Bayesian procedure was used involving a prior with a single parameter L(l,b), which varies smoothly with Galactic longitude and latitude according to a Galaxy model. The posterior is summarized with a point estimate (usually the mode) and a confidence interval (usually the 68% highest density interval). The estimation procedure is described in detail in the accompanying paper (http://www.mpia.de/homes/calj/gdr2_distances.html), which also analyses the catalogue content. The catalogue comprises one table with 1.33 billion rows and seven columns. The accompanying paper explains under what circumstances the different estimates/modality occur. These should not be mixed in any statistical analyses. Around 99.9% of all sources have result_flag=1 and modality_flag=1.1331909760 source_id Gaia source identifier, identical to the Gaia-DR2 source_id. meta.id;meta.main BIGINT indexed primary r_est Estimated distance. pc pos.distance DOUBLE indexed primary r_lo Lower bound on the confidence interval of the estimated distance. pc stat.error;stat.min;pos.distance DOUBLE r_hi Upper bound on the confidence interval of the estimated distance. pc stat.error;stat.max;pos.distance DOUBLE r_len Length scale used in the prior for the distance estimation. pc stat.fit.param;pos.distance DOUBLE result_flag Type of result. Three possible values: 0 = failed estimate (r_est, r_lo, r_hi are all NaN) ; 1 = r_est is the mode (highest if the posterior is bimodal); r_lo/r_hi define the lower/upper limits of the highest density interval (HDI) containing 68% of the posterior probability ; 2 = r_est is the median; r_lo/r_hi define the lower/upper limits of the equal-tailed interval (ETI), containing 68% of the posterior probability. meta.code.qual SMALLINT indexed modality_flag Result regime flag: number of modes in the posterior (1 or 2). meta.code SMALLINT indexed

This table contains a substantial fraction of the around 2.5 million stars in the Hipparcos and Tycho-2 catalogue.
