Panels A: maps of the dust emission (8 and 250 μm in MJy sr⁻¹) and maps of the gas components (HI in Jy beam⁻¹ km s⁻¹, CO in K km s⁻¹, Hα in dR) ofa molecular cloud of our sample (cloud number 5 in Fukui et al. 2008, nomenclature). Panels B: SEDs in the various gas phases derived from dust decomposition (see Eq. (3)) for cloud number 5, fitted with the different dust models. Blue diamonds correspond to the data with their 1σ uncertainties, whereas the red asterisks and the red continuous lines correspond to the color-corrected brightnesses and the total emission derived from the models.
