Fig. 27
Predicted IR/UV luminosity ratio as a function of the observed UV slope determined from SED fits of the B-drop sample for model A (declining SFHs) assuming the Calzetti attenuation law (green squares) or the SMC extinction law (magenta). Black triangles show the predictions for model B (constant SFR) with the Calzetti law for comparison. The solid (dashed) lines show the expected relation for galaxies with an intrinsic UV slope of β ≈ − 2.2 for the two attenuation laws.
