Dust attenuation as a function of β (same symbols as in Fig. 3). The solid line corresponds to the relation found in this work: A_FUV = 1.70 × (β + 2.5). The dashed line corresponds to the relation of Overzier et al. (2011) (their inner relation). The relation found by Murphy et al. (2011) for 24 μm selected galaxies at 0.66 < z < 2.66 and by Buat et al. (2011a) for nearby galaxies selected at 140 μm are plotted as blue solid and dotted lines, respectively.
