COng Non-Gaussian profile. The line intensity is obtained by integrating the zero power full width (ZPFW) range. In particular − 10, +20 km s−1 for CO (2–1), +1, +10 km s−1) for 13CO (2–1), and +1, +9 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.
