The ratio of the infrared luminosity density contributed from intermediate (⁠|$10.1\lt \mathrm{log}\, M_{\star }/\mathrm{M}_{\odot }\lt 11$|⁠; purple circles) and high (log M_⋆/M_⊙ > 11; orange diamonds) mass galaxies to the total IR derived from ‘total light’ stacking for cluster galaxies as a function of redshift. We compare our cluster results to the field values in the same mass bins derived from deep Herschel imaging (teal and red lines with hatched uncertainty; Viero et al. 2013) and the SIDES simulation (blue and orange lines with solid uncertainty; Béthermin et al. 2017). The shaded solid/hatched regions represent the uncertainty and scatter on this ratio; for the SIDES simulation, this is based on the known uncertainties on the simulation inputs and is likely an underestimate of the true scatter (see Section   5.3 for further details). Although the high mass cluster galaxies agree well with the field ratios at comparable mass, the intermediate mass cluster galaxies sit well below the expected contribution to the total IR from similar mass galaxies in the field.
