The Coma Cluster – I. A catalogue of magnitudes, colours, ellipticities and position angles for 6724 galaxies in the field of the Coma cluster

Abstract

We describe the measurement of isophotal magnitudes, radii, intensity profiles, ellipticities and (b–r) colours for 6724 galaxies with b26.5 < 21.0 in a 2.63 degree square area centred on the Coma cluster. The sample is considered essentially complete to b26.5 = 20.0.
