Notes.
Mass of the clump (see Table 4).
The mean value of the nearest-neighbour distances between the cores. The quoted uncertainty is the standard error of the mean, and it could be calculated for systems of three or more cores.
The local thermal Jeans length calculated for the clump temperature from Table 4.
