Abstract:
The WIde-field Nearby Galaxy-cluster Survey (WINGS) is a wide-field
and multiwavelength survey of 76 galaxy clusters in the local
Universe. The sample consists of all clusters at 0.04<z<0.07 in
both hemispheres at Galactic latitude |b|>20 selected from the ROSAT
X-ray-Brightest Abell-type Cluster Sample, the Brightest Cluster
Sample, and its extension. The original WINGS survey is based on B and
V imaging for the 76 clusters over a 34 by 34 arcminute field of view
taken with the Wide Field Cameras on the INT and the 2.2m MPG/ESO
telescopes. With the aim to cover the virial region and extend out
into the infall region, we have obtained GTO OmegaCAM imaging in the
B, and V bands over 1 by 1 degree for 45 fields covering 46 WINGS
clusters. We present the Johnson B- and V-band OmegaCAM photometry of
46 WINGS clusters. With a median seeing of 1 arcsecond in both B- and
V-bands, our 25-minutes exposures in each band typically reach the 50%
completeness level at V=23.1mag.
Description:
Observations started in October 2011 and were concluded in September
2013. The first observations were carried out during ESO period P88
with the OmegaCAM STARE-mode, splitting the total exposure time into
3x480s observations with no offsets. We adopted this observing mode to
obtain a constant signal-to-noise ratio (S/N) across the FOV, as in
the original WINGS survey. Starting from period P89, we optimised our
observing strategy, taking 5x300s exposures in DITHER-mode, with
25" and 85" offsets in horizontal and vertical direction,
respectively.
