1989PASP..101.1072v CAN E AND SO GALAXIES BE DISTINGUISHED PHOTOMETRICALLY? SIDNEY VAN DEN BERGH Dominion Astrophysical Observatory, National Research Council of Canada 5071 West Saanich Road, Victoria, BC, V8X 4M6, Canada Received 1989 August 2, revised 1989 September 19 ABSTRACT Modern CCD photometry of early type galaxies does not allow one to differentiate unambiguously between E and SO galaxies. A de Vaucouleurs law fits the major axis profiles of SO galaxies as frequently as it does those of ellipticals. The data do, however, indicate that exponential disks occur more often in SOs than they do in elliptical galaxies. Furthermore, ellipticals exhibit their maximum flattening at intermediate radii more frequently than do SO galaxies. Key words: galaxies-photometry
