Notes. The quoted physical properties of the cores were calculated by assuming the parent clump dust temperatures from Col. (2) in Table 4.

(a)

The effective radius of the core was unresolved, and hence only a lower limit to the number density could be calculated. The uncertainty in the density is taken into account in the quoted lower limit value.
