Visual attenuation, A_V ≈ A_UV/ 2.5, for the objects of this study as a function of stellar mass. The typical uncertainty on stellar mass is about ± 0.3 dex (Conroy 2013; de Barros et al. 2014; Sklias et al. 2014). Uncertainties on A_V are ≈ 0.1 − 0.2 (cf. Table 3). The dash-dotted and dotted lines show the mean relation for star-forming galaxies at z ~ 0 and z ~ 0.75 − 1.5 from Garn & Best (2010) and Domínguez et al. (2013). Two median relations for LBGs at z ~ 7 from Schaerer & de Barros (in prep.) are shown as long- and short-dashed lines. The former is derived from fitting directly M_⋆ and A_V, the latter shows the median M_⋆ and A_V values for LBGs with M₁₅₀₀ = −22 to − 18; both relations are for declining SFHs.
