- Description:
- PPM-Extended (PPMX) is a catalogue of 18 088 919 stars on the ICRS system containing astrometric and photometric information. Its limiting magnitude is about 15.2 in the GSC photometric system.

- Publisher:
- The GAVO DC team
- Description:
- The RAdial Velocity Experiment (RAVE) contains stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, chemical abundances and distances. Observations between 2003 and 2013 were used to build the five RAVE data releases.

- Title:
- SuperCOSMOS Sources
- Short Name:

- Date:

- Publisher:
- The GAVO DC team
- Description:
- The SuperCOSMOS data primarily originate from scans of the UK Schmidt and Palomar POSS II blue, red and near-IR sky surveys. The ESO Schmidt R (dec < -17.5) and Palomar POSS-I E (dec > -17.5) surveys have also been scanned and provide an early (1st) epoch red measurement. Mirrored here is the source table containing four-plate multi-colour, multi-epoch data which are merged into a single source catalogue for general science exploitation. Within the GAVO DC, some column names have been adapted to local customs (primarily positions, proper motions).

- Title:
- The fourth U.S. Naval Observatory CCD Astrograph Catalog (UCAC4)
- Short Name:
- ucac4 scs
- Date:

- Publisher:
- The GAVO DC team
- Description:
- UCAC4 is a compiled, all-sky star catalog covering mainly the 8 to 16 magnitude range in a single bandpass between V and R. Positional errors are about 15 to 20 mas for stars in the 10 to 14 mag range. Proper motions have been derived for most of the about 113 million stars utilizing about 140 other star catalogs with significant epoch difference to the UCAC CCD observations. These data are supplemented by 2MASS photometric data for about 110 million stars and 5-band (B,V,g,r,i) photometry from the APASS (AAVSO Photometric All-Sky Survey) for over 50 million stars. UCAC4 also contains error estimates and various flags. All bright stars not observed with the astrograph have been added to UCAC4 from a set of Hipparcos and Tycho-2 stars. Thus UCAC4 should be complete from the brightest stars to about R=16, with the source of data indicated in flags.

- Title:
- The Gaia-PS1-SDSS (GPS1) Proper Motion Catalog
- Short Name:
- GPS1
- Date:
- 23 Mar 2022 13:13:03
- Publisher:
- The GAVO DC team
- Description:
- 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).
19. The HSOY Catalog
- ID:

- Title:
- The HSOY Catalog
- Short Name:
- HSOY SCS
- Date:

- Publisher:
- The GAVO DC team
- Description:
- HSOY is a catalog of 583'001'653 objects with precise astrometry based on PPMXL and Gaia DR1. Typical formal errors at mean epoch in proper motion are below 1 mas/yr for objects brighter than 10 mag, and about 5 mas/yr at the faint end (about 20 mag). South of -30 degrees, astrometry is significantly worse. HSOY also contains, where available, USNO-B, Gaia, and 2MASS photometry. HSOY's positions and proper motions are given for epoch J2000. The catalog becomes severely incomplete faintwards of 16 mag in the G-band. The mean epochs are typically very close to Gaia's J2015. HSOY still contains about 0.7% spurious close "binaries" (non-matched stars) from the original USNO-B (marked with non-NULL clone). Also, failed matches within Gaia DR1 contribute another 1.5% spurious pairs (marked with non-NULL comp). In both cases, astrometry presumably is sub-standard.
