Notes. Based on the range of globule densities estimated in Table 1. Values in parenthesis are 1σ errors. (a) Assuming Tk = 100 K. (b) From 13CO (2–1) line-widths. (c) Assuming Tk = Tex(12CO). (d) Bonnor-Ebert mass for an external pressure given by Pext = Pnth(C+) + Pth(C+). (e) Jeans mass for Rg and σnth+th, g determined from 13CO (2–1).
