SED-derived SFR plotted vs. independently determined recipe SFR (see Sect. 3.3.2 for details). Two different SFR tracers are shown: FUV+TIR and Hα+24μm luminosity; see Appendix B for details. Symbols (dark-orange circles for CIGALE, blue triangles for GRASIL, and red squares for MAGPHYS) are calculated with SFR(FUV+TIR); plus signs show the recipe SFR(Hα+24μm) luminosity. 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, calculated with SFR(FUV+TIR). The robust correlations are shown as solid lines, and the identity relation by a (gray) dashed one; in each panel, the steeper power-law slope corresponds to the fit to SFR(FUV+TIR) and the shallower one to SFR(Hα+24μm) (see Table 3 for details). The rms deviations for the fit of SED-derived quantities vs. the reference ones (for SFR(FUV+TIR)) are shown by the σ value in the lower right corner of each panel; similarly, SED-fitting uncertainties are shown as vertical lines only for SFR(FUV+TIR) x values. rms deviations for SFR(Hα+24μm) are 0.25 dex, 0.18 dex, and 0.26 dex for CIGALE, GRASIL, and MAGPHYS, respectively (see Table 3).
