SFR–mass relation for galaxies in the low-density field (grey crosses), in the high-density field (green dots), cluster virial (orange diamonds), and outer members (black stars). The red dashed vertical line shows the stellar mass limit. The blue line is the fit to the relation including all the environments, and the shaded areas correspond to 1σ errors on the fitting line. Linear fits for each environment are shown separately in the figure, colour coded according to the legend. The black dashed line represents the log(sSFR) = –12 limit.
