We have obtained deep and wide field imaging of the Coma
cluster of galaxies with the CFH12K camera at CFHT in the B, V, R and
I filters. In this paper, we present the observations, data reduction,
catalogs and first scientific results.
We investigated the quality of our data by internal and external literature
comparisons. We also checked the realisation of the observational requirements
we set.
Our observations cover two partially overlapping areas of
arcmin2, leading to a total area of
deg2.
We have produced catalogs of objects that
cover a range of more than 10 mag. and are complete
at the 90% level at
,
,
and
for stellar-like objects, and at
,
,
and
for faint low-surface-brightness galaxy-like
objects.
Magnitudes are in good agreement with published values from
to
. The photometric uncertainties are of the order of 0.1 mag at
and of 0.3 mag at
.
Astrometry is accurate
to 0.5 arcsec and also in good agreement with published data.
Our catalog provides a rich dataset that can be mined
for years to come to gain new insights into the formation and
evolution of the Coma cluster and its galaxy population.
As an illustration of the data quality, we examine the
bright part of the Colour Magnitude Relation (
versus R)
derived from the catalog and find that it is in
excellent agreement
with that derived for
galaxies with redshifts in the Coma cluster, and with previous CMRs
estimated in the literature.
