This archive collects and re-publishes third-party, mostly amateur,
images of the Gaia astrometry satellite to complemement the Ground Based
Optical Tracking (GBOT) effort.
Until Gaia passivation, there is a temporary upload facility
at https://dc.g-vo.org/citigbot/q/upload/form.

Description:
The Kepler satellite has observed the Galactic center in a campaign
lasting from April until the end of June 2016 (K2/C9). The main
objective of the 99 hours for the microlensing program 097.C-0261(A)
using the ESO VLT Survey Telescope (VST) was to monitor the superstamp
(i.e., the actually downloaded region of K2/C9) in service mode for
improving the event coverage and securing some color-information. Due
to weather conditions, the majority of images were taken in the red
band. These are part of the present release.
The exact pointing strategy was adjusted to cover the superstamp with
6 pointings and to contain as many microlensing events from earlier
seasons as possible. In addition, a two-point dither was requested to
reduce the impact of bad pixels and detector gaps. Consequently, some
events were getting more coverage and have been observed with
different CCDs. The large footprint of roughly 1 square degree and the
complementary weather conditions at Cerro Paranal have lead to the
coverage of 147 events (this resource's events table), but ~60 of
those were already at baseline.
This table holds metadata for the “Patrol” and “Meteor” plates from
DASCH, i.e., very wide-field observations presumably not useful in
global discovery. These data products are therefore not re-published
through obscore. For the “narrow” plates, see the narrow_plates table.
This table holds metadata for the parts of DASCH counting as targeted
observations (plate scale below 400 arcsec/mm. “Patrol” and “Meteor”
plates in DASCH nomenclature are found in the wide_plates table.
This is a deep optical mosaic of the Fornax cluster’s core, covering
1.6 square degrees. The data were acquired with ESO/MPG 2.2m/WFI,
using a transparent filter that nearly equals the no-filter throughput
and thus provides a high signal-to-noise ratio. Based on an
approximate conversion to V-band magnitudes, the unbinned and binned
mosaics (0.24 and 0.71 arcsec/pixel) reach a median depth of 26.6 and
27.8 mag/sq.arcsec, respectively.
Digitized First Byurakan Survey (DFBS) Spectra Query Service

Description:
The First Byurakan Survey (FBS) is the largest and the first systematic
objective prism survey of the extragalactic sky. It covers 17,000 sq.deg.
in the Northern sky together with a high galactic latitudes region in the
Southern sky. The FBS has been carried out by B.E. Markarian, V.A.
Lipovetski and J.A. Stepanian in 1965-1980 with the Byurakan Observatory
102/132/213 cm (40"/52"/84") Schmidt telescope using 1.5 deg. prism. Each
FBS plate contains low-dispersion spectra of some 15,000-20,000 objects;
the whole survey consists of about 20,000,000 objects.
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.

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.
