For the brightest galaxy in each of 48 nearby clusters and 7 groups of galaxies, photoelectric measurements of V and V-r magnitudes have been made. Redshifts have been measured for those 39 clusters and 3 groups which did not have previously published redshifts. Absolute magnitudes and colors were calculated for each cluster, and the cscb dependence of the absolute magnitudes and colors was attributed to galactic absorption.
After correcting for selection effects, the ratio of total to selective absorption was found to be [...]=3.9 which is consistent with [...]=3.0. The values found for the color-excess and absorption at the galactic pole are [...]=0.016 and [...]=0.06. This value for the color-excess is in agreement with [...]=0.03 found by Sturch for the RR Lyrae stars.
