Galaxy sSFR vs. M _⋆  in three different regions of the A1763 supercluster. Open (black) circles represent all non-AGN, IR-emitting supercluster members. Filled dots identify supercluster members in the core region (red dots, top panels), in the filament region (blue dots, middle panels), in the outskirts region (green dots, bottom panels). The panels on the left are based on the z ∪ z_p sample, those on the right on the z sample. The dash-dotted line has the same meaning as in Fig. 9.
