Relation of log₁₀(sSFR)−D4000. Symbols are the same as in Fig. 13. The black lines represent the fits to the running median of the sSFRs of the galaxies of both structures A and B, calculated in bins of 5 points, and the grey-filled areas represent the 1σ deviation of the sSFRs. For active sSFRs (solid line), we sorted the points vertically, and horizontally for the suppressed sSFRs (dashed line). Upper and right histograms show the distributions of D4000 (stacked cumulative histogram) and log₁₀(sSFR), respectively, for active and suppressed populations, divided in structures A and B.
