Abstract:
This paper belongs to a series presenting the WIde Field Nearby
Galaxy-cluster Survey (WINGS). The WINGS project has collected
wide-field, optical (B,V), and near-infrared (J,K) imaging as well as
medium resolution spectroscopy of galaxies in a sample of 76 X-ray
selected nearby clusters (0.04<z<0.07) with the aim of establishing a
reference sample for evolutionary studies of galaxies and galaxy
clusters.
We present the U-band photometry of galaxies and stars in the fields
of 17 clusters of the WINGS sample. We also extend the original B- and
V-band photometry (WINGS-OPT) for 9 and 6 WINGS clusters to a larger
field of view. We used both the new and already existing B-band
photometry to obtain reliable (U-B) colors of galaxies within three
fixed apertures in kpc. To this aim, we particular care the
astrometric precision in the reduction procedure. Since not all the
observations were taken in good transparency conditions, the
photometric calibration was partly obtained by relying on the SDSS and
WINGS-OPT photometry for the U- and optical bands, respectively.
We provide U-band (also B- and V-band, where possible) total
magnitudes of stars and galaxies in the fields of clusters. For
galaxies only, the catalogs also provide geometrical parameters and
carefully centered aperture magnitudes. The internal consistency of
magnitudes was checked for clusters imaged with different cameras,
while the external photometric consistency was obtained by comparison
with the WINGS-OPT and SDSS surveys.
The photometric catalogs presented here add the U-band information to
the WINGS database for extending the spectral energy distribution
(SED) of the galaxies, in particular in the ultraviolet (UV)
wavelengths which are fundamental for deriving the star formation rate
(SFR) properties.
Description:
The observations were made with three different wide-field cameras:
- the 90prime camera at the 90inches (2.3m) BOK telescope (90prime@BOK,
Kitt Peak), in 2 runs: 2000-06-20/22 and 2006-11-22/23
- the Wide Field Camera at the 2.5m Isaac Newton Telescope (WFC@INT),
in 1 run: 2005-05-10/14
- the Large Binocular Camera at the Large Binocular Telescope (LBC@LBT).
on the 5 nights 2007-03-12, 2007-05-19, 2008-06-04, 2008-06-07 and
2008-06-08
- For one cluster (Abell 970) we used imaging data from the WFI@MPG
(ESO2.2 archive), performed on 2000-02-27/29
All clusters have been imaged in the U-band, and many clusters have
also been imaged in the optical (B,V) bands.

Global notes:
Note (G1): Aperture flag as follows:
0 = free
1 = aperture centered on WINGS_OPT (galaxies in common with WINGS)
2 = aperture centered on BOK B-band (galaxies not in common with WINGS)
