Nuclear and circumnuclear cold molecular gas properties.
| Region | r | i | CO(3−2) flux | Mgas |
|---|---|---|---|---|
| (pc) | (°) | (Jy km s−1) | (M⊙) | |
| Torus | 32 | 67 | 1.4 | 8.2 × 105 |
| Nuclear | 50 | 85 | 0.9 | 7.2 × 105 |
| Circumnuclear | 200 | 85 | 21 | 1.7 × 107 |
| Ring | 720 | 85 | 270 | 6.2 × 108 |
Notes. We used different brightness temperature ratios for the torus and the other regions, namely, TBCO(3−2)/TBCO(1−0) = 2.9 for the torus, TBCO(3−2)/TBCO(1−0) = 2.0 for the nuclear and circumnuclear regions, and TBCO(3−2)/TBCO(1−0) = 0.7 for the ring. See text for details.
