Left: L8/LIR vs. sSFR divided by that of the main sequence of the RXJ 0152 member galaxies (red crosses) compared with those of the NEP-Deep field galaxies (grey circles). The red squares indicate spectroscopically confirmed member galaxies, while red crosses indicate the member galaxies without spectroscopic redshift. The green broken line indicates the average of the red points in 0.5 dex bins where errors are calculated with standard deviation divided by the square root of the number of galaxies in each bin. The blue dotted line indicates the average from the NEP-Deep field. The redshift range of the NEP-Deep field galaxies is restricted to z = 0.76−0.925. Right: relation between L8/LIR and LIR. Symbols are the same as the left panel. The grey, cyan, and magenta dotted lines indicate the results from Chary & Elbaz (2001) at z = 0, and Nordon et al. (2012) at z = 1 and z = 2, respectively.
