Dust temperature distribution in the MC at the reference MC. The PDFs are weighted by mass and luminosity, with ΔT ≈ 7.1 K and 50 bins. The left panel refers to the simulated MC in D20, the middle panel to the homogeneous model in S20 and the right panel to the radiation–pressure model. Circles indicate the median of each distribution, whereas the dotted lines bracket the 16th and 84th percentiles.
