This services provides 1D spectra from DR5 of LAMOST (Large Sky Area
Multi-Object Fiber Spectroscopic Telescope) through SSAP;
data is served both in VO-standard SDM and, via datalink, the original
SDSS-inspired FITS described in

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.
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).

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.
