A photometric catalogue of galaxies in the cluster Abell 85

We present two catalogues of galaxies in the direction of the rich cluster Abell 496. The rst one in- cludes 3879 galaxies located in a region of roughly 1.3 from the cluster centre. It has been obtained from a list of more than 35000 galaxy candidates detected by scan- ning part of a Schmidt photographic plate taken in the bJ band. Positions are very accurate in this catalogue but magnitudes are not. This led us to perform CCD imag- ing observations in the V and R bands to calibrate these photographic magnitudes. A second catalogue gives a list of galaxies with CCD magnitudes in the V (239 galaxies) and R (610 galaxies) bands for a much smaller region in the centre of the cluster. These two catalogues will be combined with a redshift catalogue of 466 galaxies (Durret et al. 1999) to investi- gate the cluster properties at optical wavelengths (Durret et al. in preparation), as a complement to previous X-ray studies by a member of our group (Pislar 1998).
