Abstract
We have determined surface-brightness profiles for all galaxies down to magnitude B=16 in the central region of the Fornax cluster. Using redshift data, we have determined the distributions of surface brightnesses for both the whole sample and for cluster disc galaxies only. Although both distributions peak at extrapolated central surface brightnesses ~21.7B mag/arcsec2 (the canonical result), it is shown that they are, in fact, consistent with very broad distributions of disc central surface brightness once selection effects and the effects of bulge contamination of the profile are taken into account. This is in agreement with the conclusion drawn from fainter samples of galaxies in the cluster area. In addition, we confirm that the vast majority of disc galaxies have scalelengths less than 2 kpc.
