Same as Fig. B.1, but for different radiation mixes. Beside the reference γ = 0 case, we show results for γ = 1 and various values for α and ΔU; and for models taking into account the biases described by Priestley & Whitworth (2020), assuming that grains exposed to the attenuated radiation field have the THEMIS properties (case 1) or those of the CMM grain mixture (case 2; see text for details). For clarity, in the left panel the α = 1.5 SED is shown for I_ν(250 μm)/I_ν(500 μm)=5.5 only, and the α = 1.3 SED for I_ν(250 μm)/I_ν(500 μm)=7.5 only.
