Fits to the SED of the SC1-8 clumps. Single-component fits only consider flux at wavelengths longer than 65 µm to avoid a contribution from unrelated diffuse warm gas to the clumps’ SEDs. SCUBA 450 µm emission was not considered as we found it to systematically underestimate the flux of all clumps. Flux densities at 8 µm and 65 µm are considered as upper limits due to the possible contributions of PAHs and very small grains.
