Fig. 2
IR/UV luminosity ratio versus UV slope β for our objects. The typical uncertainty on LIR/LUV due to the unknown dust temperature is about ± 0.25 dex; uncertainties in β are typically ± (0.3 − 0.5) (cf. Sect. 4.1). The long-dashed, solid, and dashed lines show the relations for different attenuation/extinction laws for comparison (cf. Calzetti et al. 2000; Takeuchi et al. 2012).
