Left panel: as Fig. 7 except for ⟨log age⟩_L. The inner gradient shows a clear dependence with Hubble type, that seems to be stronger than with the galaxy mass. Sb–Sbc–Sc galaxies have larger inner gradients with CBe than with GMe, but both sets of models show a similar dependence with Hubble type. Right panel: the inner gradient of ⟨log age⟩_L as a function of galaxy mass. Colors and symbols are the same as in Fig. 7.
