Abstract:
Photometric observations are presented for 8747 galaxies in the fields
of 28 clusters with redshifts in the range 0.05<z<0.11 and spanning a
wide range in Abell richness class. The primary motivation for this
study is to provide a nearby sample of clusters whose galaxy
populations can be used to provide an anchor point for evolutionary
studies of cluster galaxy populations.
Description:
Observations for this program were carried out at the University of
Warsaw 1.3m Telescope at the Las Campanas Observatory (Chile), during
the nights of 1999 April 13 through 19.

Note (1): Galaxies are identified as [BSL2004] JHHMMSS.s+DDMMSS.s in Simbad
Note (2): The final photometry was taken into the AB system Oke & Gunn
(1983ApJ...266..713O 1983ApJ...266..713O), for which we used VAB=V+0.011, RAB=R+0.199
and IAB=I+0.456 (Fukugita et al., 1995PASP..107..945F 1995PASP..107..945F). The galactic
extinction was accounted for and it was determined from the extinction
maps from Schlegel et al. (1998ApJ...500..525S 1998ApJ...500..525S) and translated into
our colors as E(V-R)=0.78, E(B-V), E(V-I)=1.6*E(B-V) (Binney &
Merrifield, 1998, Galactic Astronomy (Princeton: Princeton Univ. Press)).
