cds-question@unistra.frsurveysastrometryproper-motionsvisible-astronomytrigonometric-parallaxGaia Data Release 1 (DR1) contains astrometric results for more than 1 billion stars brighter than magnitude 20.7 based on observations collected by the Gaia satellite during the first 14 months of its operational phase. For stars in common with the Hipparcos and Tycho-2 catalogues, complete astrometric single-star solutions are obtained by incorporating positional information from the earlier catalogues. For other stars only their positions are obtained, essentially by neglecting their proper motions and parallaxes. The results are validated by an analysis of the residuals, through special validation runs, and by comparison with external data. For about two million of the brighter stars (down to magnitude ~11.5) we obtain positions, parallaxes, and proper motions to Hipparcos- type precision or better. For these stars, systematic errors depending for example on position and colour are at a level of +/-0.3 milliarcsecond (mas). For the remaining stars we obtain positions at epoch J2015.0 accurate to ~10 mas. Positions and proper motions are given in a reference frame that is aligned with the International Celestial Reference Frame (ICRF) to better than 0.1mas at epoch J2015.0, and non-rotating with respect to ICRF to within 0.03mas/yr. The Hipparcos reference frame is found to rotate with respect to the Gaia DR1 frame at a rate of 0.24mas/yr.2016A&A...595A...1Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/I/337CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/259 : The Tycho-2 Catalogue (Hog+ 2000)archives.esac.esa.int/gaia : Gaia Home Pagehttp://1016243957.rsc.cdn77.org/Gaia : Download Tgas and Gaia SourcesIsVariantFormOfGaia DR1 at ESA: https://doi.org/10.5270/esa-ogmeulahttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=I/337https://vizier.iucaa.in/viz-bin/VizieR-2?-source=I/337http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=I/337https://vizier.cds.unistra.fr/viz-bin/votable?-source=I/337https://vizier.iucaa.in/viz-bin/votable?-source=I/337http://vizieridia.saao.ac.za/viz-bin/votable?-source=I/337GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table I/337/gaia (GaiaSource data)https://vizier.cds.unistra.fr/viz-bin/conesearch/I/337/gaia?https://vizier.iucaa.in/viz-bin/conesearch/I/337/gaia?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/337/gaia?GETtext/xml+votable180.050000true44.9961522093670.0056163477550.005555555555555556Hips catalogue for table I/337/gaiahttps://hipscat.cds.unistra.fr/HiPSCatService/I/337/gaiaCone search capability for table I/337/tgas (TGAS: Subset of GaiaSource comprising those stars in the Hipparcos and Tycho-2 Catalogues for which a full 5-parameter astrometric solution has been possible in Gaia Data Release (TgasSource))https://vizier.cds.unistra.fr/viz-bin/conesearch/I/337/tgas?https://vizier.iucaa.in/viz-bin/conesearch/I/337/tgas?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/337/tgas?GETtext/xml+votable180.050000true45.03433035440.23539164880.005555555555555556Hips catalogue for table I/337/tgashttps://hipscat.cds.unistra.fr/HiPSCatService/I/337/tgasCone search capability for table I/337/tgasptyc (TGAS supplement with BT and VT magnitudes)https://vizier.cds.unistra.fr/viz-bin/conesearch/I/337/tgasptyc?https://vizier.iucaa.in/viz-bin/conesearch/I/337/tgasptyc?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/337/tgasptyc?GETtext/xml+votable180.050000true45.03433035440.23539164880.005555555555555556Cone search capability for table I/337/cepheid (Cepheid stars identified in table VariableSummary as classification="CEP")https://vizier.cds.unistra.fr/viz-bin/conesearch/I/337/cepheid?https://vizier.iucaa.in/viz-bin/conesearch/I/337/cepheid?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/337/cepheid?GETtext/xml+votable180.050000true80.4417418279-66.98619008760.005555555555555556Cone search capability for table I/337/rrlyrae (RRLyrae stars identified in table VariableSummary as classification="RRLYR" (Rrlyrae))https://vizier.cds.unistra.fr/viz-bin/conesearch/I/337/rrlyrae?https://vizier.iucaa.in/viz-bin/conesearch/I/337/rrlyrae?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/337/rrlyrae?GETtext/xml+votable180.050000true68.2155894525-66.77273043390.005555555555555556Cone search capability for table I/337/qso (*Auxilliary Quasar Solution for the QSOs that were matched to ICRF2 sources (qso_icrf2))https://vizier.cds.unistra.fr/viz-bin/conesearch/I/337/qso?https://vizier.iucaa.in/viz-bin/conesearch/I/337/qso?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/337/qso?GETtext/xml+votable180.050000true0.0849978345-32.3503429220.005555555555555556Gaia5/8277-8278 8281-8284 8293 8295 8304-8305 8307 9370 9381-9383 9385-9386 9392 6/33087 33103 33107 33116-33118 33123 33140 33144-33146 33177 33179 33201-33202 33204-33205 33208-33209 33211 33224-33225 33232 33234 33250-33252 33258 33262 33540 33601 33606 33611 33792 37439 37470 37475 37478-37479 37484-37486 37488 37491-37492 37497 37502 37518-37519 37522-37523 37539 37548-37549 37552-37554 37556-37557 37572 37574-37577 37579 37581 37584-37586 37592 389121.9867573869263685e-19 5.101838343667421e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/I/337?format=asciiOpticaldefaultI/337/gaiaGaiaSource dataRA_ICRSRight ascension (ICRS) at epoch 2015.0 (ra)degpos.eq.ra;meta.maine_RA_ICRSStandard error of right ascension (ra_error)masstat.error;pos.eq.rafloatDE_ICRSDeclination (ICRS) at epoch 2015.0 (dec)degpos.eq.dec;meta.maine_DE_ICRSStandard error of declination (dec_error)masstat.error;pos.eq.decfloatSolIDSolution ID (solution_id) (G1)meta.id;meta.versionSourceSource ID (source_id) (G2)meta.id;meta.mainindexedRandomIRandom index used to select subsets (random_index) (G3)meta.codePlx?
