Notes. Column 1 gives the name of the core observed. Columns 2 and 3 give the kinetic temperatures of the gas derived from the 12CO J=3 → 2 data and the RADEX models constrained by the rarer isotopologue lines, respectively, while Col. 4 gives the difference between the temperatures. The 13CO column density, N13, from the best fitting RADEX model is given in Col. 5 while the corresponding CO depletion factor is given in Col. 6. The values in brackets are the uncertainties.
