Distribution of stellar mass M_* and sSFR of massive galaxies at different clustercentric distances r. Only isolated regions were selected. The dashed line indicates the conventional division between star-forming and quiescent used in some other works (Franx et al. 2008). In the top left corner of each panel, the fraction of star-forming galaxies (SFR > 0.02 M_⊙ yr⁻¹) in each region is shown. The contours show regions containing 68% and 95% of galaxies. The color range is normalised to the total number of galaxies in each panel. Results are shown at low redshift (z = 0.25).
