Abstract:
In this paper we introduce the deepest and most extensive ultraviolet
extragalactic source catalogs of the Virgo Cluster area to date.
Archival and targeted GALEX imaging is compiled and combined to
provide the deepest possible coverage over ∼120deg2 in the NUV
(lambdaeff=2316Å) and ∼40deg2 in the FUV (lambdaeff=1539Å)
between 180°≤RA≤195° and 0°≤DE≤20°. We measure the
integrated photometry of 1770 extended UV sources of all galaxy types
and use GALEX pipeline photometry for 1,230,855 point-like sources in
the foreground, within, and behind the cluster. Extended source
magnitudes are reliable to mUV∼22, showing a ∼0.01σ difference
from their asymptotic magnitudes. Point-like source magnitudes have a
1σ standard deviation within ∼0.2mag down to muv∼23. The
point-like source catalog is cross-matched with large optical
databases and surveys including the SDSS DR9 (>1 million Virgo Cluster
sources), the Next Generation Virgo Cluster Survey (NGVS; >13 million
Virgo Cluster sources), and the NED (∼30,000 sources in the Virgo
Cluster). We find that 69% of the entire UV point-like source catalog
has a unique optical counterpart, 11% of which are stars and 0.01%
(129) are Virgo cluster members that are neither in the VCC nor part
of the bright CGCG galaxy catalog (i.e., mpg<14.5). These data are
collected in three catalogs containing the UV extended sources, the UV
point-like sources, and the most relevant optical parameters of
UV-optically matched point-like sources for further studies from SDSS.
The GUViCS catalogs provide a unique set of data for future work on UV
and multiwavelength studies in the cluster and background
environments.
Description:
These catalogs are based on GALEX NUV and FUV source detections in and
behind the Virgo Cluster. The detections are split into catalogs of
extended sources and point-like sources.
The UV Virgo Cluster Extended Source catalog (UV_VES.fit) provides the
deepest and most extensive UV photometric data of extended galaxies in
Virgo to date. If certain data is not available for a given source
then a null value is entered (e.g. -999, -99). UV point-like sources
are matched with SDSS, NGVS, and NED and the relevant photometry and
further data from these databases/catalogs are provided in this
compilation of catalogs.
The primary GUViCS UV Virgo Cluster Point-Like Source catalog is
UV_VPS.fit. This catalog provides the most useful GALEX pipeline NUV
and FUV photometric parameters, and categorizes sources as stars,
Virgo members, and background sources, when possible. It also provides
identifiers for optical matches in the SDSS and NED, and indicates if
a match exists in the NGVS, only if GUViCS-optical matches are
one-to-one. NED spectroscopic redshifts are also listed for GUViCS-NED
one-to-one matches. If certain data is not available for a given
source a null value is entered. Additionally, the catalog is useful
for quick access to optical data on one-to-one GUViCS-SDSS matches.The
only parameter available in the catalog for UV sources that have
multiple SDSS matches is the total number of multiple matches, i.e.
SDSSNUMMTCHS. Multiple GUViCS sources matched to the same SDSS
source are also flagged given a total number of matches,
SDSSNUMMTCHS, of one. All other fields for multiple matches are set
to a null value of -99. In order to obtain full optical SDSS data
for multiply matched UV sources in both scenarios, the user can
cross-correlate the GUViCS ID of the sources of interest with the full
GUViCS-SDSS matched catalog in GUV_SDSS.fit.
The GUViCS-SDSS matched catalog, GUV_SDSS.fit, provides the most
relevant SDSS data on all GUViCS-SDSS matches, including one-to-one
matches and multiply matched sources. The catalog gives full SDSS
identification information, complete SDSS photometric measurements in
multiple aperture types, and complete redshift information
(photometric and spectroscopic). It is ideal for large statistical
studies of galaxy populations at multiple wavelengths in the
background of the Virgo Cluster. The catalog can also be used as a
starting point to study and search for previously unknown UV-bright
point-like objects within the Virgo Cluster. If certain data is not
available for a given source that field is given a null value.

Note (1): These SDSS parameters or measurements are taken from the r' data
or made in the r' aperture.
Note (2): Better of De Vaucouleurs/exponential magnitudes in the given band.
Note (3): Linear combination of De Vaucouleurs+exponential magnitudes.
Note (4): Parameter is calculated when excluding the QSO fit.
Note (6): Classifications are based on features in the objects spectrum, and
can be one of the following classifications codes: GALAXY, QSO, or STAR.
Note (7): Photometric redshift from the SDSS 'neural network' algorithm.
Note (8): Photometric redshift from the SDSS 'random forest' algorithm.

Global Notes:
Note (G1): the SDSS photometric types are:
0 = unknown
1 = cosmic ray
2 = defect
3 = galaxy
4 = ghost
5 = known object
6 = star
7 = trail
8 = sky
9 = not a type
