PCA-derived Log(M_dust) vs. model SED-derived and “independently”-derived (here MBB) Log(M_dust) for KINGFISH galaxies. The identity relation as a (gray) dashed line as described in the text. and the σ values of the four PCAs range from (0.28 dex for CIGALE to 0.4 dex for GRASIL), with mean σ ∼ 0.3; the gray region shows identity ±1σ. As in previous figures, open symbols correspond to galaxies with low sSFR [Log(sSFR/yr⁻¹) ≤ −10.6], and filled symbols to high sSFR [Log(sSFR/yr⁻¹) > −10.6]. Horizontal error bars show the uncertainties in the SED-fitted parameters (usually smaller than the symbol size).
