Distribution of redshift (left panel), stellar mass (middle panel), and offset from the MS (right panel) for the PHIBSS2 z = 0.5 − 0.8 sample presented here, displayed in red. The offset from the MS is defined as δMS = sSFR/sSFR_MS(z, M_⋆), where sSFR_MS(z, M_⋆) is the analytical prescription for the centre of the MS proposed in the compilation by Speagle et al. (2014). In the right panel, the solid black line indicates δMS = 1 and the grey shaded area shows the ∼0.3 dex scatter of the MS. While the PHIBSS2 z = 0.5 − 0.8 sample is highlighted in red, the dashed line corresponds to the parent 3D-HST distribution at z = 0.5 − 0.8 displayed in Fig. 1, with 10 <  log(M_⋆/M_⊙)< 11.8 and |log(δMS)| <  1 (i.e. within 1 dex of the MS line), normalized to match the same number of galaxies. The dip at low redshift is probably due to either sky frequencies that made redshift determination more difficult or to cosmic variance. The mean and median stellar mass for the z = 0.5 − 0.8 subsample is log(M_⋆/M_⊙)=10.7.
