LBG-Mβ1 and LBG-Mβ2 results in the IRX–β_UV (top panels) and IRX–M_* (bottom panels) planes. Top left panel: LBG-Mβ1 are shown in green; the tonalities represent the two different bins in M_*, 9.75 <  log(M_* [M_⊙]) <  10.65 (light green filled square) and 10.65 <  log(M_* [M_⊙]) <  11.5 (dark green filled circles). Top right panel: LBG-Mβ2 results are shown in red; the tonalities represent the increase of the M_* from 9.75 (light red) to 11.50 (dark red). The filled squares represent the bluer β_UV bin and the filled circles the redder β_UV bin. Bottom left panel: LBG-Mβ1 are shown in green; the tonalities represent the increase of the β_UV from −1.7 (light green) to 0.5 (dark green). The filled squares represent the low M_* bin and the filled circles the high M_* bin. Bottom right panel: LBG-Mβ2 results are shown in red; the tonalities represent the two different bins in β_UV, −1.7 <  β_UV <  −0.5 (light red filled square) and −0.5 <  β_UV <  0.5 (dark red filled circles). The gray points in all diagrams represent the LBG-Mβ results that are not highlighted in color.
