b Gaussian fit.

ng Non-Gaussian profile. The line intensity is obtained by integrating the zero power full width (ZPFW) range. In particular, −15, +30 km s−1 for CO (2 – 1), +3, +10 km s−1) for 13CO (2–1), and +3, +10 km s−1 for C18O (2-1) (see Figure A.6). The value has to be considered a lower limit given the presence of absorption features.
