Two-colour photometry of a sample of faint galaxies
Abstract
Two-color photographic photometry has been carried out on a total sample of 3664 galaxies in two fields, each 1.27 degrees square. The results indicate the existence of an excess of high redshifted (z greater than 0.30) blue galaxies implying a recent evolutionary trend. They also show a population of nearby (z less than 0.08) dwarf galaxies, mostly red with a minimum space density of about 1 per cu Mpc.
