Notes. θmaj and θmin: major and minor axes of the deconvolved components of the Gaussian fits to the continuum components; PA: position angle; Sν: integrated flux density from the deconvolved fits; α: spectral index; β: dust emissivity spectral index; Td: dust temperature assuming isothermal and optically thin dust, which may not be the case for the C component; τν: optical depth; Md: dust mass.
