a Optical depth of the C18O(2-1) emission, estimated from the 13CO(2-1) to C18O(2-1) line intensity ratio at the systemic velocity.
b Clump mass estimated from the C18O(2-1) emission using the area under the whole emission line, and the spatial area delimited by the half power contour. $T_{{\rm ex}}$ assumed to be between 20 and 80 K.
c Virial mass, computed using Eq. (6) of Fontani et al. (2002).
d Clump mass derived from the (sub)mm dust emission measured by the cited authors.
e Rotational velocity; projected values (i.e. lower limits).
f Dynamical mass of the clump, estimated using Eq. (3).
