SFR of centrals as a function of their stellar mass, for SFR estimates from, respectively, Herschel/PACS fluxes (red circles) and SED modeling (black squares). Our adopted parametrization of the main sequence at z = 1.8 is shown as a gray line, with the 0.5 dex limit shown by dashed lines. The SFRs shown here have been corrected according to the difference in normalization between the main sequence at z = 1.8 and the redshift of the objects.
