Observed relation between M_dust and SFR in our DSFGs, shown for the whole sample (binned means, shown as black circles) and divided on SB and MS galaxies (shaded in dark cyan and orange, respectively). The known, empirically based scaling relation between T_dust − SFR − M_dust (Genzel et al. 2015) are overlaid with dashed lines. Different colours correspond to their fixed T_dust, as indicated in the legend. The best fit for local and intermediate redshift ULIRGs (Rowlands et al. 2014) are displayed with dotted and dot-dashed line, respectively.
