Notes. (a) For all the sources but G23.44-0.18, G31.28+0.06, and G35.20-1.74 (where the optical depths of both ammonia transitions have been derived, see Table 5), we have assumed optically thin emission for the NH3(2, 2) line. (b) Given the spatial resolution of the Medicina antenna, the spectra collect the contributions due to both A and B cores (see Figs. 7-10).
