The median profile of the sSFR, Σ_sSFR, for late-type galaxies for different mass bins as a function of the environment: field galaxies (left panels), galaxies in pairs (central panels), and galaxies in groups (right panels). Solid lines represent the median in each radial bin. Vertical error bars were computed using the bootstrap re-sampling technique. The number of galaxies contributing to each median profile is quoted. Dashed lines in the upper (lower) panels show the median Σ_sSFR profiles of spirals galaxies without AGNs (bars). For clarity, we excluded the vertical error bars in these profiles.
