Notes. The clump numbers correspond to those in Fig. 3. MNH2 is the mass deduced from the column density map (Fig. 4b). For the M25′′, M, and M6000 AU estimates, temperatures are assumed to be between 17−25 K. For clumps 4, 5 and 6, M6000 AU is derived from the peak flux density without substracting any emission. M25′′ is the mass over an angular diameter of 25″, M is the derived mass of a putative protostellar envelope after a Gaussian fit and M6000 AU is the corresponding mass over an area of 6000 AU after a Gaussian fit of the peak emission.
