$^{b}$ {Clump mass estimated from the C$^{18}$O(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. (\cite{fontani02}).}\\
$^{d}$ {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. (\ref{mdyn}).}\\
