Best-fitting results for FIR SEDs for 77 and 158 μm continuum emission, using Eqs. (2)–(3) and adopting the β_d obtained in Fig. 3, for the three components identified in the analysis from Sect. 4.1: HZ10-C (left panel), HZ10-W (middle panel), and the bridge (right panel). Conventions are the same as in Fig. 3. As shown in Figs. 1 and 2, HZ10-C and the bridge have lower 77 μm continuum emission, compared to that for HZ10-W (although still within the uncertainties); this may be reflecting a strong UV dust absorption in HZ10-W, which translates into a higher T_SED temperature when compared to those of the other two components (although all of them with the same temperature within 1σ).
