Notes. Comparing the spectra between 12CO J = 2−1 and 13CO J = 1−0 and channel maps of 12CO J = 2−1, we suggest that the dips in the 12CO 3−2 profiles of molecular cores #2, #4, #6, and #11 do not indicate self-absorption. Here we just consider the spectra main component associated to each clump of N22.
