Notes. In the third and fifth columns we list the error on column densities without considering the calibration error (ΔN). In the sixth column we list the corresponding 14N/15N isotopic ratios. Uncertainties have been derived as explained in the caption of Table 3. In the last column we list the kinetic temperatures of the clumps derived from Fontani et al. (2015a). * average value for the specific evolutionary stage.
