gavo@ari.uni-heidelberg.de+49 6221 54 1837starssurveysastrometryproper-motions This catalog combines Gaia DR1, Pan-STARRS 1, SDSS and 2MASS astrometry to compute proper motions for 350 million sources across three-fourths of the sky down to a magnitude of mr≈20. Positions of galaxies from Pan-STARRS 1 are used to build a reference frame for PS1, SDSS, and 2MASS data. Gaia DR1 is adapted to that reference frame by exploiting that locally, proper motions are linear. GPS1 has a characteristic systematic error of less than 0.3 mas/yr, and a typical precision of 1.5−2.0 mas/yr. The proper motions have been validated using galaxies, open clusters, distant giant stars and QSOs. In comparison with other published faint proper motion catalogs, GPS1's systematic error (<0.3 mas/yr) is about 10 times better than that of PPMXL and UCAC4 (>2.0 mas/yr). Similarly, its precision (~1.5 mas/yr) is an improvement by ∼ 4 times relative to PPMXL and UCAC4 (∼6.0 mas/yr). For QSOs, the precision of GPS1 is found to be worse (∼2.0−3.0 mas/yr), possibly due to their particular differential chromatic refraction (DCR).2017ApJS..232....4Thttp://dc.g-vo.org/gps1/q/cone/infoResearchIsServedByGAVO Data Center TAP servicehttp://dc.g-vo.org/gps1/q/cone/formhttps://dc.g-vo.org/gps1/q/cone/formhttp://dc.g-vo.org/gps1/q/cone/scs.xml?https://dc.g-vo.org/gps1/q/cone/scs.xml?GETapplication/x-votable+xmlRARight Ascension (ICRS decimal)degpos.eq.rarealDECDeclination (ICRS decimal)degpos.eq.decrealSRSearch radiusdegrealobj_idUnique object identifier (this is not the Pan-STARRS1 identifier).meta.id;meta.mainintegermagrr-band PSF magnitude from Pan-STARRS1 DR1magphot.mag;em.opt.RrealresponseformatFile format requested for output.meta.code.mimecharmaxrecMaximum number of records returned.
