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

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.
TheoSSA provides spectral energy distributions based on model
atmosphere calculations. Currently, we serve results obtained using
the Tübingen NLTE Model Atmosphere Package (TMAP) for hot compact
stars.

A catalogue of 541 nearby (within 10pc of the sun) stars, brown
dwarfs, and confirmed exoplanets in 336 systems, as well 21
candidates, compiled from SIMBAD and several other sources. Where
available, astrometry and photometry from Gaia eDR3 has been inserted.
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`).
Parts I and III of the sixth fundamental catalog, a catalog of
high-precision astrometry for bright stars combining centuries of
ground-based observations as reflected in FK5 with HIPPARCOS
astrometry.
The result contains, in particular for the proper motions,
statistically significant improvements of the Hipparcos data und
represents a system of unprecedented accuracy for these 4150
fundamental stars. The typical mean error in pm is 0.35 mas/year for
878 basic stars, and 0.59 mas/year for the sample of the 3272
additional stars.
