Stacked profile of the sSFR Σ_sSFR for late-type galaxies as a function of the environment. Each panel corresponds to a different mass bin. Galaxies in groups are shown in red lines, galaxies in pairs in green lines, and field galaxies in blue lines. Lines represent the median in each radial bin. Vertical error bars are as in Fig. 4. Field galaxies and galaxies in pairs have been shifted by 0.03 and −0.03 on the x-axis, respectively.
