Dependence of the HST‐resolved bulge Sérsic index ﹩n_{hst}﹩ on global properties of the parent galaxy: (a) ﹩n_{hst}﹩ vs. galaxy morphological type index T. (b) ﹩n_{hst}﹩ vs. the bulge Sérsic index ﹩n_{\mathrm{gb}\,}﹩ obtained from ground‐based data (APB95). (c) ﹩n_{hst}﹩ vs. the bulge‐to‐disk ratio. (d) Bulge index ﹩n_{hst}﹩ vs. the bulge K‐band absolute magnitude. Filled circles: Bulges (this work). Crosses: Bulges from the de Jong (1996) sample, as analyzed by Graham (2001; see his Fig. 14).
