The properties of the bulge+disk fits to galaxies with HST photometry and a measured velocity dispersion. We plot the ratio ae/Re of the semi-major effective scale length ae of the best-fit Sersic profile to the circularized effective radius Re of the best-fit B+D model (top), the bulge-to-total ratio B/T (middle), and the Sersic index nSer (bottom) as a function of the ellipticity 1 − be/ae (where be is the semi-minor effective scale length) of the Sersic fit. Objects with B/T > 0.5 are plotted in red, the remainder in blue. Symbols code the morphology: filled ellipses show T ≤ −4, filled circles crossed by a line −3 ≤ T ≤ 0, spirals T > 0.
