Notes. Columns are: temperature, T, and source mass, M, both with errors, σ, bolometric luminosity, L, reference size (R_dec), and mean density, ⟨ n_H₂ ⟩. Also, the table has the most likely core type for the object, whether protostellar, bound starless, or unbound (see Sect. 6), and a potential identity, from comparisons with other observations of the region. We note that the mass errors given here are solely from the SED fit, and do not include the 25% errors from flux-scaling and distance estimates.
