E-GALAXIES AND SO-GALAXIES AS A SINGLE POPULATION

In a recently published paper, the results of our so-called ''quantita tive morphology'' of a nearly complete local sample of 108 unbarred E and SO classified galaxies were analyzed, assuming that most of these form a single population of two-components objects, i.e. containing bo th a disk and a spheroid. The results of this work are summarized here . Then the discussion is extended to another complete sample of 111 ga laxies in the Coma cluster, including nearly 100 early-type objects. P rovided that allowance is made for much enlarged seeing effects, and t hat the morphological criteria are made identical, the population of t he early-type galaxies in the cluster environment appears remarkably s imilar to the local one.
