Lick indices (Hβ vs. [MgFe]′, left panels, and Mgb vs. [MgFe]′, right panels) extracted at r < re/2 for the dwarf sample. From top to bottom, the galaxies were separated according to their group membership: RR143, RR210, RR216, and RR242. For RR242_13326, [MgFe]′ is a lower limit. The data are compared with SSP models of metallicities Z = 0.0004, 0.004, 0.008, 0.02, 0.05, ages  =  13, 9, 6, 5, 4, 3, 2, 1.5 Gyr, and [α/Fe]  =  –0.4, 0., 0.4.
