For all panels inside the grey box: distributions of the physical properties estimated for our DSFGs from the SED fitting with CIGALE. From top left to bottom right: goodness of fit expressed as reduced χ²; galaxy redshift; stellar mass; SFR; IR luminosity; dust mass; and galaxy linear offset from the MS (in log scale). Bottom right panel: linear offset of the galaxy’s observed SFR to the SFR expected from the modelled MS (Δ_MS in log scale) as a function of redshift. A border between the sources considered as MS and SB DSFGs is indicated by a horizontal, dashed line.
