Description:
This catalogue provides distances estimates (and uncertainties therein)
for 1.33 billion stars over the whole sky brighter than about G=20.7.
These have been estimated using the parallaxes (and their uncertainties)
from Gaia DR2. A Bayesian procedure was used involving a prior
with a single parameter L(l,b), which varies smoothly with Galactic
longitude and latitude according to a Galaxy model. The posterior is
summarized with a point estimate (usually the mode) and a confidence
interval (usually the 68% highest density interval). The estimation
procedure is described in detail in the `accompanying paper`_,
which also analyses the catalogue content.

Description:
FIRST (Faint Images of the Radio Sky at Twenty-cm) is a project designed to produce the radio equivalent of the Palomar Observatory Sky Survey over 10,000 square degrees of the North and South Galactic Caps. The catalogue covers a total of about 9033 square degrees of sky (8422 square degrees in the north Galactic cap and 611 square degrees in the south Galactic cap.)
This service returns the most important Gaia DR3 gaia_source columns
together with robust geometric and photogeometric distances for the
~1.47 billion objects in Bailer-Jones et al's distance catalogue.

Description:
The Galaxy Evolution Explorer (GALEX) satellite is a NASA mission led by the California Institute of Technology to investigate how star formation in galaxies evolved from the early Universe up to the present. GALEX uses microchannel plate detectors to obtain direct images in the near-UV (NUV) and far-UV (FUV) and a grism to disperse light for low resolution spectroscopy
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.
