Correlation between the V-band attenuation derived by BD and SED fitting (total, old, and young stars, in the left, middle, and right panels, respectively). Each galaxy is represented by a different colour. A solid line stands for the one-to-one relation. Left panel: A_V, BD versus the total attenuation estimated by CIGALE (A_V, SED). Points with Σ_SFR [${\mathrm{M}}_{\odot }{\mathrm{Gyr}}^{-1}{\mathrm{pc}}^{-2}$] > 100 are shown in white. The best-linear fit to the latter points, assuming a zero intercept, is plotted with a dashed line and its uncertainty is indicated by the shaded grey area. A dash-dotted and a dotted line represent the corresponding results from Calzetti et al. (2000) and Kreckel et al. (2013). Middle panel: A_V, BD versus the attenuation of the old stellar component as estimated by CIGALE (A_V, SED^old). Right panel: A_V, BD versus the attenuation of the young stellar component as estimated by CIGALE (A_V, SED^young). The plus-minus 0.5 dex area is defined by the dashed grey lines.
