Notes. ^(a) Total flux above 5σ. For source G08b, G31 and G10, subtraction of free-free emission is considered (details in Appendix B). ^(b) Effective radius is defined as , where Area stands for the emission region above5σ for each 1.2 mm map, i.e., non-deconvolved averaged size. ^(c)Dust temperature is assumed to be equal to gas temperature T(r) obtained and refined in Sect. 3.4, and the average temperature is calculated by averaging over pixels that have continuum emission above 5σ. ^(d) Average density calculated from and R_eff. ^(e) For clump G18, the calculation for two cores are given. In the Abel inversion calculation which assumes spherical symmetry, only the central, more massive core is considered. So and are omitted for the secondary core.
