SFR–M_⋆ relation of the NUVrJ star-forming galaxies selected in this work, colour-coded by redshift over 0.1 < z < 4.5. At fixed M_⋆ and redshift, SFR_IR measurements are converted from the L_IR obtained from IR/sub-mm SED-fitting (circles). Downward arrows indicate 3σ upper limits. For completeness, we also show the SFR_IR + UV estimates by combining SFR_IR with UV-uncorrected SFRs (open squares). Solid lines mark the evolving MS relation between SFR_IR + UV and M_⋆ at different redshifts (Schreiber et al. 2015). We observe an excellent agreement with the MS, even below M_⋆ ∼ 10^9.5 M_⊙ that relies upon a linear extrapolation from Schreiber et al. (2015) that is not constrained by previous data.
