A_FUV plotted against FUV − NUV. The sample is restricted to 267 galaxies with an error in FUV − NUV lower than 0.2 mag, and the linear regression is plotted as a dashed black line. Galaxies with L_IR > 10¹¹   L_⊙ are plotted as empty red circles. Relations from previous studies are overplotted: Salim et al. (2007) (green dot-dashed line), Seibert et al. (2005) (blue dotted line), and Meurer et al. (1999) (black solid line). Standard errors in A_FUV are plotted for 1/4 of the objects.
