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).
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.

The Lepine-Shara Catalog of High Proper Motion Stars

The GAVO DC team
Description:
The LSPM catalog is a comprehensive list of 61,977 stars north of the
J2000 celestial equator that have proper motions larger than 0.15"/yr
(local-background-stars frame).
Positions are given with an accuracy of <~100 mas at the 2000.0 epoch,
and absolute proper motions are given with an accuracy of ~8 mas/yr.
The catalog is estimated to be over 99% complete at high Galactic
latitudes (|b|>15{deg}) and over 90% complete at low Galactic
latitudes (|b|>15{deg}), down to a magnitude.
The LIFE Target Star Database contains information useful
for the planned `LIFE mission`_ (mid-ir, nulling
interferometer in space). It characterizes possible
target systems including information about stellar,
planetary and disk properties. The data itself is mainly
a collection from different other catalogs.
Note that LIFE's target database is living
data. The content – and to some extent even structure – of these
tables may change at any time without prior warning.

The 2MASS Point Source Catalogue, short a couple of exotic fields. We
provide this data mainly for matching with other catalogs within our
TAP service.
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`).
