IRX–β_UV diagram. Lines show different IRX–β_UV relations: the well-known local starburst galaxies calibration (M99; triple-dot-dashed line), the aperture correction of M99 relation by Takeuchi et al. (2012; dashed line), and the relation derived from a FIR stacking analysis over the same LBG sample (AM16; dotted blue line). In addition, we plot the IRX–β_UV results from LBGs at redshifts, z ∼ 3 (Koprowski et al. 2018, orange dots) and 2 <  z <  3 (Bouwens et al. 2016, gray dots), star-forming galaxies at redshifts, 2 <  z <  3 (McLure et al. 2018, green dots) and 1.5 <  z <  2.5 (Reddy et al. 2018, black dots), and a mass selected sample at redshift z ∼ 3 (Bourne et al. 2017, blue dots). The downward triangles represent upper limits.
