SED-derived L_FUV plotted vs. independently determined L_FUV with extinction corrections derived from Spitzer and Herschel photometric data (see Sect. 3.3.4 for details). The σ values shown in the lower right corner of each panel correspond to the mean deviations of the L_FUV fit (see Table 3). The lines are as in Fig. 4. As in Fig. 5, filled symbols correspond to high specific SFR (Log(sSFR/yr⁻¹) > −10.6), and open ones to low specific SFR (Log(sSFR/yr⁻¹) ≤ −10.6), as noted in the legend in the upper left corners. This sSFR limit corresponds roughly to the lowest quartile in the KINGFISH galaxies, and also to the inflection in the SFMS by Salim et al. (2007).
