PHOTOMETRY OF GROUPS OF GALAXIES .2. THE NGC-972 GROUP

A nearby group of galaxies, centered at the spiral galaxy NGC 972 and conspicuously rich in faint dwarf spheroidal galaxies, has been invest igated photometrically on the B and V plates, obtained with the Tauten burg 2m Schmidt telescope. For ten certain and probable group members the equivalent B and V brightness profiles have been extracted. Integr ated magnitudes and mean colours of faint group members have been esti mated. Typically, the dwarfs show a ''subexponential'' (i.e. a convex curvature over the linear radius) surface brightness profile and often a central excess. Their equivalent profiles are reasonably well fitte d by modified isothermal (King) models.
