Deprojected distance from the dominant subgroup galaxy (either CenA or M 83) plotted as a function of: (upper panel) the fraction of stars formed in the past 0–1 Gyr (f_1G), 1–4 Gyr (f_4G) and 4–14 Gyr (f_14G); (lower panel) the ratio of SFR to the lifetime average SFR over the last 100 Myr (b₁₀₀), 500 Myr (b₅₀₀) and 1 Gyr (b_1G). The black open circles represent the CenA subgroup late-type dwarfs and the black filled circles are M 83 subgroup members. Grey squares indicate the old distances for three of the CenA subgroup members, while black open circles for the same galaxies are new distances that we recompute because they are actually closer to M 83 than to CenA (see also Fig. 7).
