SED-derived L_TIR plotted vs. independently determined L_TIR from Spitzer and Herschel photometric data (see Sect. 3.3.4 for details). In each panel, the DL07 L_TIR values are shown by filled circles (CIGALE), filled triangles (GRASIL), and filled squares (MAGPHYS), and those from Galametz et al. (2013) by +. The σ values shown in the upper left corner of each panel correspond to the mean deviations of the L_TIR fit with the DL07 values (see Table 3). The lines are as in Fig. 4, and SED-fitting uncertainties are shown as vertical lines only for the DL07 x values (but they are typically smaller than the symbol size).
