cds-question@unistra.fr['Astrometric data']The ASC is a compilation produced for the Gaia mission. We have combined data from the following catalogs or datasets to produce a homogenous list of positions, proper motions, photometry in a blue and red band and estimates of the magnitudes in the Gaia G and G_RVS bands: Tycho2, UCAC4, Hipparcos, PPMXL, GSC2.3 and Sky2000. Originally ASC sources were selected from the Initial Gaia Source List (IGSL, I/324). However, here we produce a cleaner catalog starting from the bright source catalogs and using the following criteria: 1) The candidate must be in the Tycho2, UCAC4, Hipparcos or Sky2000 catalog. 2) The Gaia G magnitude must be brighter than 13.4. 3) The star must be isolated from other objects of similar magnitudes 4) The object must not be in the Washington Double Star catalog 5) If a healpix 6th region has more than 1000 objects the magnitude limit is reduced to reduce the number of objects in that region. Since the ASC was produced independently from the IGSL using different procedures there is not a direct 1 to 1 match between ASC and IGSL entries. We have matched the ASC to the IGSL and found that 9 out of the 8 million entries do not have a clear match. Since there may still remain ambiguous matches in the 8 million matched objects, we decided to assign the sourceIDs of the IGSL with the adjustment that the runningnumber is equal to the IGSL runningnumber + 320000. Included Catalogs: Tycho2, UCAC4, Sky2000, HIPPARCOS for candidates and the PPMXL, GSC2.3 were used to calculating magnitudes.2015yCat.6145....0Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/VI/145CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/324 : The Initial Gaia Source List (IGSL) (Smart, 2013)VI/137 : GaiaSimu Universe Model Snapshot (Robin+, 2012)V/145 : SKY2000 Master Catalog, Version 5 (Myers+ 2006)I/305 : The Guide Star Catalog, Version 2.3.2 (GSC2.3) (STScI, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VI/145https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VI/145http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VI/145https://vizier.cds.unistra.fr/viz-bin/votable?-source=VI/145https://vizier.iucaa.in/viz-bin/votable?-source=VI/145http://vizieridia.saao.ac.za/viz-bin/votable?-source=VI/145GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table VI/145/attitude (Gaia Attitude Star Catalog (ASC))https://vizier.cds.unistra.fr/viz-bin/conesearch/VI/145/attitude?https://vizier.iucaa.in/viz-bin/conesearch/VI/145/attitude?http://vizieridia.saao.ac.za/viz-bin/conesearch/VI/145/attitude?GETtext/xml+votable180.050000true45.1321250.1377620.005555555555555556Hips catalogue for table VI/145/attitudehttps://hipscat.cds.unistra.fr/HiPSCatService/VI/145/attitudeGaia0/0-11 6/https://cdsarc.cds.unistra.fr/viz-bin/moc/VI/145?format=asciidefaultVI/145/attitudeGaia Attitude Star Catalog (ASC)r_pmProper motion source (sourceMu) (1)meta.ref;pos.frameintsourceIdSource identifiermeta.id;meta.mainindexedRAJ2000Right Ascension at J2000 (alpha)degpos.eq.ra;meta.maine_RAJ2000Error in Right Ascension (alphaError)arcsecstat.error;pos.eq.rafloatDEJ2000Declination at J2000 (delta)degpos.eq.dec;meta.maine_DEJ2000Error in Declination (deltaError)arcsecstat.error;pos.eq.decfloatmagBJGSC2.3 B mag (magBJ)magphot.mag;em.opt.Bfloatindexede_magBJStandard error on magBJ (magBJError)magstat.errorfloatr_magBJBJ magnitude source (sourceMagBJ) (2)meta.ref;pos.frameintmagRFGSC2.3 R mag (magRF)magphot.mag;em.opt.Rfloatindexede_magRFStandard error on magRF (magRFError)magstat.errorfloatr_magRFRF magnitude source (sourceMagRF) (2)meta.ref;pos.frameintmagGG mag estimate (magG)magphot.mag;em.optfloatindexede_magGError in G mag estimate (magGError)magstat.errorfloatr_magGG magnitude source (sourceMagG) (2)meta.ref;pos.frameintmagGrvsGrvs mag estimate (magGrvs)magphot.mag;em.opt.Ifloatindexede_magGrvsError in Grvs mag estimate (magGrvsError)magstat.errorfloatr_magGrvsGrvs magnitude source (sourceMagGrvs) (2)meta.ref;pos.frameintEpRAMean Epoch of Right Ascension (alphaEpoch)yrtime.epochdoubleEpDEMean Epoch of Declination (deltaEpoch)yrtime.epochdoublesrcPosition source (sourcePosition) (1)meta.ref;pos.frameintpmRA?
