Same as in Fig. 7, but now the top row shows the radial SSFR profiles for the PCA-based classes of S0 galaxies, while the bottom row does the same for S0s classified according to the ΔMS scheme. Color coding is consistent: S0–MS (blue), S0–GV (green), S0–QS (red), S0–AC+TR (light-blue), S0–PS (red), E (black), Sa+Sb (orange), Sc+Sd (purple), SF (magenta), and all S0 galaxies (brown).
