SED-derived M_star plotted vs. independently determined M_star from the recipe IRAC 3.6 μm luminosities (see Sect. 3.3.1 for details). The Wen et al. (2013) M_star values are shown by filled (dark-orange) circles (CIGALE), filled (blue) triangles (GRASIL), and filled (red) squares (MAGPHYS), and the constant M/L ones by +; the σ values shown in the upper left corner of each panel correspond to the mean deviations from the fit of M_star with the Wen et al. (2013) method (see Table 3). Similarly, SED-fitting uncertainties are shown as vertical lines only for the Wen et al. (2013)x values, and are usually smaller than the symbol size. The robust correlation relative to the Wen et al. (2013) values is shown as a solid line, and the identity relation by a (gray) dashed one.
