Dust SED obtained for each source from the derived dust temperatures; dust emissivity spectral indexes, β; and H₂ column density, N_H2. For each source the dust SED of the two extreme values for the corresponding dust temperature range are indicated by blue and green dashed lines. The possible dust SEDs corresponding to the intermediate values of dust temperatures are represented by the grey shaded area. For FIR6c-a, FIR2, MMS5, and CSO3-b the dust SEDs corresponding to the derived range of T_rad and/or T_bol are also represented by red dashed lines and a red shaded area. Measured flux densities are represented by black stars. Lower limitsare represented by coloured arrows.
