- Description:
- The catalogue ARIHIP has been constructed by selecting the 'best data' for a given star from combinations of HIPPARCOS data with Boss' GC and/or the Tycho-2 catalogue as well as the FK6. It provides 'best data' for 90 842 stars with a typical mean error of 0.89 mas/year (about a factor of 1.3 better than Hipparcos for this sample of stars).

- Publisher:

- Description:
- MWSC presents a list of 3006 Milky Way Stellar Clusters (MWSC), found in the 2MAst (2MASS with Astrometry) catalogue. The target list was compiled on the basis of present-day lists of open, globular and candidate clusters. For confirmed clusters we determined a homogeneous set of astrophysical parameters such as membership, angular radii of the main morphological parts, mean cluster proper motions, distances, reddenings, ages, tidal parameters, and sometimes radial velocities.

- Description:
- MWSC-e14a ("MWSC extension 2014a") is a catalogue of 139 new open clusters at high Galactic latitudes (\|b\|>20 deg) including lists of candidate members. It extends the Kharchenko et al. 'Catalog of Milky Way Star Clusters'. The target list was compiled as density enhancements found in the 2MASS point source catalogue. For confirmed clusters we determined a homogeneous set of astrophysical parameters such as membership, angular radii of the main morphological parts, proper motion, distance, reddening, age, and tidal parameters. .. _Catalog of Milky Way Star Clusters: http://dc.g-vo.org/mwsc/q/clu/form

- 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).

- The fifth U.S. Naval Observatory CCD Astrograph Catalog (UCAC5)
- Short Name:
- UCAC 5
- Date:

- Publisher:
- The GAVO DC team
- Description:
- New astrometric reductions of the US Naval Observatory CCD Astrograph Catalog (UCAC) all-sky observations were performed from first principles using the TGAS stars in the 8 to 11 magnitude range as reference star catalog. Significant improvements in the astrometric solutions were obtained and the UCAC5 catalog of mean positions at a mean epoch near 2001 was generated. By combining UCAC5 with Gaia DR1 data new proper motions on the Gaia coordinate system for over 107 million stars were obtained with typical accuracies of 1 to 2 mas/yr (R = 11 to 15 mag), and about 5 mas/yr at 16th mag. Proper motions of most TGAS stars are improved over their Gaia data and the precision level of TGAS proper motions is extended to many millions more, fainter stars. The database table uses actual NULLs for missing photometry, and all angular coordinates have been homogenised to degrees.

- Title:
- The fourth U.S. Naval Observatory CCD Astrograph Catalog (UCAC4)
- Short Name:
- ucac4 scs
- Date:
- 23 Mar 2022 13:13:16
- 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).
15. The HSOY Catalog

- 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. More information is available at http://dc.g-vo.org/hsoy.

- Description:
- PPMXL is a catalog of positions, proper motions, 2MASS- and optical photometry of 900 million stars and galaxies, aiming to be complete down to about V=20 full-sky. It is the result of a re-reduction of USNO-B1 together with 2MASS to the ICRS as represented by PPMX. This service additionally provides improved proper motions computed according to Vickers et al, 2016 (:bibcode:`2016AJ....151...99V`).
