Notes. Columns are the clump name (for 1.3 mm cores only), offset position relative to the map center, peak flux, total flux, the effective radius after deconvolution with the beam of the mm core, total gas mass for a temperature Tkin estimated from NH3 observations, peak H2 column density, average gas density over Reff, total mass, virial mass from NH2D observations, the alpha parameter as defined in Eq. (2), and an aperture mass for an aperture size of 37 000 AU. 37 000 AU corresponds to the beam of the more distant source G29.96e. The aperture mass is underestimated up to a factor 2 when aperture size is very similar to the beam. Comments:

(a)

Mass estimates based on an assumed temperature of 16 K, since measured value has a very high error (>30%).

(b)

NH2D spectra at these offsets show clearly more than one velocity component. We did not consider these positions because of the following, (i) poor two-component HFS fit in CLASS in one case, (ii) difficulty of associating a particular component to the dust.

(c)

No NH2D detection.

(d)

mm4 is barely resolved with peak emission just above 5σ. Given the biases in a typical interferometer image, this might be spurious.
