Reconstructed spectra (left) and maps (right) of the 353 GHz dust intensities, I_d,i, of the seven clouds, ℂ_i (i = 1, …, 7), identified in the G139 region. The spectra are averaged over the 26 × 26 pixels of the (l, b) grid. The total spectra are plotted in black solid line, while the spectra of the individual kinematic components are plotted in color, using the same colors as in Fig. 5 and two different linestyles to distinguish the two gas tracers (solid for Hi and dashed for CO).
