Relative distribution of GOODS-S sources as a function of AGN L(IR) fraction, L(60)/L(100) and L(160)/L(1.6), as indicated by the labeling in the right-hand panels, in different IR luminosity bins. Histograms are normalized to the number of sources in each L(IR) bin. Left/right panels refer to a 24 μm selection and sources detected by Herschel, respectively. Infrared luminosity bins are 1 dex wide, i.e. they cover ranges 10⁸ − 10⁹, 10⁹ − 10¹⁰, etc.
