This is gaia_source from the Gaia Data Release 3, stripped to just
enough columns to enable basic science (but therefore a bit faster and
simpler to deal with than the full gaia_source table).
Note that on this server, there is also The gedr3dist.main, which
gives distances computed by Bailer-Jones et al. Use these in
preference to working with the raw parallaxes.
This server also carries the gedr3mock schema containing a simulation
of gaia_source based on a state-of-the-art galaxy model, computed by
Rybizki et al.
The full DR3 is available from numerous places in the VO (in
particular from the TAP services ivo://uni-heidelberg.de/gaia/tap and
ivo://esavo/gaia/tap).
This is a “light” version of the full Gaia DR2 gaia_source table,
containing the original astrometric and photmetric columns with just
enough additional information to let careful researchers notice when data
is becomes uncertain and the full error model should be consulted. The
full DR2 is available from numerous places in the VO (in particular from
the TAP services ivo://uni-heidelberg.de/gaia/tap and
ivo://esavo/gaia/tap).
This table also includes a column containing the Renormalized Unit Weight
Error RUWE (GAIA-C3-TN-LU-LL-124-01), a robust measure for the
consistency of the solution.
On this TAP service, there is the table gdr2dist.main containing
distances computed by Bailer-Jones et al (:bibcode:`2018AJ....156...58B`).
If in doubt, use these instead of the parallaxes provided here.
This catalogue is a simulation of the Gaia EDR3 stellar content using
Galaxia (a tool to sample stars from a Besancon-like Milky Way model),
3d dust extinction maps and the latest PARSEC Isochrones. It is
mimicking the Gaia DR2 data model and an apparent magnitude limit of
G=20,7. Extinctions and photometry in different bands have also been
included in a supplementary table as well as uncertainty estimates
using scaled GDR2 errors. Additional magnitude limit per HEALpix maps
are provided, based on the mode in the magnitude distribution of Gaia
DR2 data.
This service delivers (most of) the datasets held at
GAVO Data Center. In addition to the default (nonstandard)
way of just appending accrefs to the get access URL, there is also a
very simple datalink service here that, for each dataset, essentially
just gives the dataset itself and possibly a preview. More advanced
datalink services might be available.
Some datasets may be embargoed, in which case the access yields a 403.
Credentials for individual files may be obtained by contacting the
site operators.
This is a form-based service allowing users to run simple
queries against GAVO Data Center's ivoa.obscore table, with
some nods to users looking of data near the optical waveband.
For serious use, the `obscore table`_ should be queried through
TAP.
Note that queries without spatial constraints may take time out. You
probably ought to switch to async TAP if you really want to run such
queries.
