Comparison between our standard model and a single black body fit. The spatial resolution is R4 (54 pc). The x axis is the mass starlight averaged intensity  ⟨ U ⟩  of the “standard model”. The y axis is the ratio between the dust derived with a single black body fit and with the “standard model” , for the same pixel. The color code of the pixel density and the binning of the trend are similar to Fig. 13.
