Relative uncertainty of dust masses (defined as σ(M_dust) /M_dust) at the GOODS-S depth, based on DL07 SED modeling, as a function of redshift and SFR. Color coding is as in Fig. 2. The dotted, solid, and dashed lines indicate the position of the MS of star formation at different values of stellar mass (Elbaz et al. 2011). These values were obtained from the dependence of the sSFR_MS on redshift by adopting log (M^∗/M_⊙) = 10.0, 10.5, and 11.0, respectively.
