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.
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.

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).
This table is a subset of GaiaSource comprising those stars in the
Hipparcos and Tycho-2 Catalogues for which a full 5-parameter
astrometric solution has been possible in Gaia Data Release 1. This is
possible because the early Hipparcos epoch positions break some
degeneracies due to the limited Gaia time coverage. This table
contains a substantial fraction of the around 2.5 million stars in the
Hipparcos and Tycho-2 catalogue. Many stars have been excluded due to
several reasons, such as saturation, cross-match errors or bad
astrometric solution. All rows have Gaia solution id
1635378410781933568.
The fifth U.S. Naval Observatory CCD Astrograph Catalog (UCAC5)

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.
The first U.S. Naval Observatory Astrometric Robotic Telescope Catalog
URAT1 star catalog
Short Name:

Description:
URAT1 is an observational catalog at a mean epoch between 2012.3 and
2014.6; ot covers the magnitude range 3 to 18.5 in R-band, with a
positional precision of 5 to 40 mas. It covers most of the northern
hemisphere and some areas down to -24.8° in declination.
In the GAVO data center, we left out all columns originating from
cross matches with other catalogs; on-the fly crossmatches can be done
in our TAP service.
