Notes.

(a)

The continuum at 1.33 mm results from the merging of the 1.28 mm and 1.38 mm continuum bands.

(b)

The mean frequency was calculated assuming a S(ν) ∝ ν−2.2 emission spectra accurately describes the interstellar medium spectral energy distribution slope in frequency range considered.

(c)

The noise level of the CO transition lines are given per channel, and the channels have a width of 0.3 km s−1.

(d)

The continuum and 12CO(2–1) fluxes are integrated within the area given by the 5σ level. The 13CO(2–1) flux is integrated within the area given by the 3σ level.
