cds-question@unistra.frastrometryproper-motionsWe combined data from the Two-Micron All Sky Survey (2MASS) and USNO-A2.0 catalogues in order to derive the absolute proper motions of about 280 million stars distributed all over the sky excluding a small region near the Galactic Centre, in the magnitude range 12<B<19mag. The proper motions were derived from the 2MASS Point Sources and USNO-A2.0 catalogue positions with a mean epoch difference of about 45 years for the Northern hemisphere and about 17 years for the Southern one. The zero-point of the absolute proper motion frame (the 'absolute calibration') was specified with the use of about 1.45 million galaxies from 2MASS. Most of the systematic zonal errors inherent in the USNO-A2.0 catalogue were eliminated before the calculation of proper motions. The mean formal error of absolute calibration is less than 1mas/yr.2011MNRAS.416..403Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/I/319CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/252 : The USNO-A2.0 Catalogue (Monet+ 1998)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/320 : SPM 4.0 Catalog (Girard+, 2011)I/323 : International Celestial Reference Frame 2, ICRF2 (Ma+, 2009)I/305 : The Guide Star Catalog, Version 2.3.2 (GSC2.3) (STScI, 2006)II/246 : 2MASS All-Sky Catalog of Point Sources [PSC] (Cutri+ 2003)VII/233 : The 2MASS Extended sources [XSC] (IPAC/UMass, 2003-2006)J/A+A/494/799 : Large Quasar Astrometric Catalogue (LQAC) (Souchay+, 2009)J/A+A/537/A99 : Large Quasar Astrometric Catalogue 2 (LQAC-2) (Souchay+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=I/319https://vizier.iucaa.in/viz-bin/VizieR-2?-source=I/319http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=I/319https://vizier.cds.unistra.fr/viz-bin/votable?-source=I/319https://vizier.iucaa.in/viz-bin/votable?-source=I/319http://vizieridia.saao.ac.za/viz-bin/votable?-source=I/319GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table I/319/xpm (formatted catalog (on a total of 313,610,083 sources))https://vizier.cds.unistra.fr/viz-bin/conesearch/I/319/xpm?https://vizier.iucaa.in/viz-bin/conesearch/I/319/xpm?http://vizieridia.saao.ac.za/viz-bin/conesearch/I/319/xpm?GETtext/xml+votable180.050000true44.9960530.0055630.005555555555555556Hips catalogue for table I/319/xpmhttps://hipscat.cds.unistra.fr/HiPSCatService/I/319/xpm0/0-11 6/8.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/I/319?format=asciidefaultI/319/xpmformatted catalog (on a total of 313,610,083 sources)IDXPM ID (ZZZ-NNNNNNN) (4)meta.id;meta.maincharRAICRSRight Ascension (ICRS, epoch 2000.0) (RA) (5)degpos.eq.ra;meta.mainDEICRSDeclination (ICRS, epoch 2000.0) (DEC) (5)degpos.eq.dec;meta.mainpmRApProper Motion in RA with PSC (MuRAp) (1)mas/yrpos.pm;pos.eq.radoublepmDEpProper Motion in DEC with PSC (MuDEp) (1)mas/yrpos.pm;pos.eq.decdoublepmRAxProper Motion in RA with XSC (MuRAx) (1)mas/yrpos.pm;pos.eq.radoublepmDExProper Motion in DEC with XSC (MuDEx) (1)mas/yrpos.pm;pos.eq.decdoubleFmag?
