Median of n_Bulge as a function of sSFR for the field galaxies (blue) and the central (solid) and satellite (dashed) HB11 (orange), HB12 (green), and HB13 (red) groups. The central and satellite galaxies in all environments closely follow the field galaxies. Where the central HB11 galaxies appear to rise above the other environments, the uncertainties are such that this rise is not significant. Error bars for satellite galaxies are omitted for clarity of the plot but are comparable to the errors of the central galaxies.
