Table 4.

Integrated intensities in Jy km s−1 of the observations and the dense disk cloud model.

Line Iobs Imodel
CO(2−1) 1.6 1.2
CO(3−2) 5.3 7.2
CO(6−5) 31.3 55.4
HCN(3−2) 2.5 2.7
HCN(4−3) 5.3 5.4
HCO+(3−2) 0.8 0.6
HCO+(4−3) 3.0 1.0 (a)

Notes.

(a)

The intercloud gas model (Sect. 4.2.3) yields Imodel = 2.0 Jy km s−1.

(b)

The intercloud gas model (Sect. 4.2.3) yields Imodel = 0.26 Jy km s−1. IR pumping is assumed for the HCN and HCO+ lines.
