AbstractAn analysis of estimated galaxy magnitudes, morphology, and group angular size for the case of 100 compact groups of galaxies indicates that (1) there is no correlation between group density and magnitude difference between first- and second-ranked galaxies, (2) there is no preferred morphological type for the first-ranked galaxies, many of which are spiral, (3) the groups contain fewer spirals than a comparable samp ...
