Abstract

We have carried out CCD photometry in the Cousins B and R bands of 15 galaxies in the Canes Venatici I cloud. Total magnitudes, effective radii, effective surface brightnesses, as well as galaxy radii at various isophotal levels in both colors were determined. Best-fitting exponential parameters and color gradients are also given for these galaxies. The photometric parameters presented here will analyzed in a forthcoming paper, together with previously published data for nearby dwarf galaxies.
