Relationship between IR luminosity (thus SFR) and dust mass for our sample, with the symbols colored by the temperature of the cold dust component. The figure is a projection of the dust plane we find between L_IR , M_dust , and T_cold . Symbols – which denote the sSFR classification of the galaxies – are the same as in Fig. 10. The black dashed lines are the fits to the L_IR –M_dust plane for cold component dust temperature bins centered at (bottom to top) 20, 22, 24, 26 and 28 K. The purple line shows the relationship between L_IR and M_dust obtained by da Cunha et al. (2010) where dust temperature is not taken into account. The typical error is shown in the top right of the plot.
