cds-question@unistra.frsurveysstellar-distanceextinctionCombining the precise parallaxes and optical photometry delivered by Gaia's second data release with the photometric catalogues of Pan-STARRS1, 2MASS, and AllWISE, we derived Bayesian stellar parameters, distances, and extinctions for 265 million of the 285 million objects brighter than G=18. Because of the wide wavelength range used, our results substantially improve the accuracy and precision of previous extinction and effective temperature estimates. After cleaning our results for both unreliable input and output data, we retain 137 million stars, for which we achieve a median precision of 5% in distance, 0.20mag in V-band extinction, and 245K in effective temperature for G<=14, degrading towards fainter magnitudes (12%, 0.20mag, and 245K at G=16; 16%, 0.23mag, and 260K at G=17, respectively). We find a very good agreement with the asteroseismic surface gravities and distances of 7000 stars in the Kepler, K2-C3, and K2-C6 fields, with stellar parameters from the APOGEE survey, and with distances to star clusters. Our results are available through the ADQL query interface of the Gaia mirror at the Leibniz-Institut fuer Astrophysik Potsdam (gaia.aip.de) and as binary tables at data.aip.de. As a first application, we provide distance- and extinction-corrected colour-magnitude diagrams, extinction maps as a function of distance, and extensive density maps. These demonstrate the potential of our value-added dataset for mapping the three-dimensional structure of our Galaxy. In particular, we see a clear manifestation of the Galactic bar in the stellar density distributions, an observation that can almost be considered direct imaging of the Galactic bar.2019A&A...628A..94Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/I/349CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/328 : AllWISE Data Release (Cutri+ 2013)II/349 : The Pan-STARRS release 1 (PS1) Survey - DR1 (Chambers+, 2016)https://data.aip.de/projects/starhorse2019.html : Catalog Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=I/349https://vizier.iucaa.in/viz-bin/VizieR-2?-source=I/349http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=I/349https://vizier.cds.unistra.fr/viz-bin/votable?-source=I/349https://vizier.iucaa.in/viz-bin/votable?-source=I/349http://vizieridia.saao.ac.za/viz-bin/votable?-source=I/349GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table I/349/starhorse (Starhorse catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/I/349/starhorse?https://vizier.iucaa.in/viz-bin/conesearch/I/349/starhorse?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/349/starhorse?GETtext/xml+votable180.050000true44.996153684160.005615806210.0055555555555555560/0-11 6/https://cdsarc.cds.unistra.fr/viz-bin/moc/I/349?format=asciidefaultI/349/starhorseStarhorse catalogRA_ICRSBarycentric right ascension (ICRS) at Ep=2015.5 (from Gaia DR2)degpos.eq.ra;meta.mainZGalStarHorse Galactocentric Cartesian Z co-ordinate, derived from dist50 and assuming R0=8.2kpckpcsrc.redshift;pos.galactocentric;pos.cartesiandoubleRGalStarHorse Galactocentric planar distance, derived from XGal and YGalkpcpos.distance;pos.galactocentricdoubleruweGaia DR2 renormalised unit-weight error (Lindegren et al., 2018A&A...616A...2L)meta.code.qualdoubleDE_ICRSBarycentric declination (ICRS) at Ep=2015.5 (from Gaia DR2)degpos.eq.dec;meta.mainSourceGaia DR2 source numbermeta.id;meta.mainindexedFlagPhotoList of filter used as input for StarHorse (SH_PHOTOFLAG) (1)meta.code.errorcharFlagPlxInforms about the precision of the Gaia DR2 parallaxes (SH_PARALLAXFLAG) (2)meta.code.errorcharFlagGaiaDescribes the overall astrometric and photometric quality of the Gaia DR2 data for each star in a three-digit flag (SH_GAIAFLAG) (3)meta.code.errorcharFlagOutSimilar to SH_GAIAFLAG, consists of several digits that inform about the fidelity of the StarHorse output parameters (SH_OUTFLAG) (4)meta.code.errorchardist05StarHorse distance, 5th percentilekpcpos.distancedoubledist16StarHorse distance, 16th percentilekpcpos.distancedoubledist50StarHorse distance, 50th percentilekpcpos.distancedoubledist84StarHorse distance, 84th percentilekpcpos.distancedoubledist95StarHorse distance, 95th percentilekpcpos.distancedoubleAV05StarHorse line-of-sight extinction at {lambda}=5420{AA}, 5th percentilemagphys.absorptiondoubleAV16StarHorse line-of-sight extinction at {lambda}=5420{AA}, 16th percentilemagphys.absorptiondoubleAV50StarHorse line-of-sight extinction at {lambda}=5420{AA}, 50th percentilemagphys.absorptiondoubleAV84StarHorse line-of-sight extinction at {lambda}=5420{AA}, 84th percentilemagphys.absorptiondoubleAV95StarHorse line-of-sight extinction at {lambda}=5420{AA}, 95th percentilemagphys.absorptiondoubleAG50StarHorse line-of-sight extinction in the G band, derived from AV50 and teff50magphys.absorptiondoubleteff16StarHorse effective temperature, 16th percentileKphys.temperature.effectivedoubleteff50StarHorse effective temperature, 50th percentileKphys.temperature.effectivedoubleteff84StarHorse effective temperature, 84th percentileKphys.temperature.effectivedoublelogg16StarHorse surface gravity, 16th percentilelog(cm.s**-2)phys.gravitydoublelogg50StarHorse surface gravity, 50th percentilelog(cm.s**-2)phys.gravitydoublelogg84StarHorse surface gravity, 84th percentilelog(cm.s**-2)phys.gravitydoublemet16StarHorse metallicity, 16th percentilephys.abund.Fedoublemet50StarHorse metallicity, 50th percentilephys.abund.Fedoublemet84StarHorse metallicity, 84th percentilephys.abund.Fedoublemass16StarHorse stellar mass, 16th percentilesolMassphys.massdoublemass50StarHorse stellar mass, 50th percentilesolMassphys.massdoublemass84StarHorse stellar mass, 84th percentilesolMassphys.massdoubleABP50StarHorse line-of-sight extinction in the GBP band, 50th percentile, derived from AV50 and teff50magphys.absorptiondoubleARP50StarHorse line-of-sight extinction in the GRP band, 50th percentile, derived from AV50 and teff50magphys.absorptiondoubleBP-RP0?
