IRX of ASAGAO sources as a function of their stellar mass (red circles). We also show the ALMA-non-detected ZFOURGE sources (Straatman et al. 2016) within the ASAGAO field, ALESS sources (da Cunha et al. 2015), and ALMA-selected sources from Dunlop et al. (2017). The thick shaded blue line shows the consensus relation compiled by UV-selected galaxies at |$z$| ∼ 2–3 (Bouwens et al. 2016). (Color online)
