Bibliographic Code:


Major- and minor-axis profiles given previously for 105 galaxies of all morphological types are decomposed into bulge and disk components. In addition, three model-independent parameters which measure the mean surface brightness, scale radius, and degree of light concentration are derived. The best correlations are found between Hubble type, concentration, bulge/disk ratio, and mean surface brightness. Correlations between the individual bulge and disk parameters generally show large scatter. The properties of S0 galaxies are inconsistent with their having been formed from spiral galaxies via gas depletion; their properties are intermediate between those of ellipticals and spirals. Most elliptical galaxies probably do not form by the merging of disk galaxies. The difficulty of distinguishing between elliptical and S0 galaxies in some cases is emphasized.
