Properties of the 12CO (2–1) detected in emission.
| Parameter | Value | |
|---|---|---|
| SCO (2−1) | total | 174 ± 17 Jy km s−1 |
 |
7.3 × 107 K km s−1 pc2 | |
| M (H2) | αCO = 0.8 M⊙ ⋅ (K km s−1 pc−2)−1 | 3.2 × 108 M⊙ |
| αCO = 4.6 M⊙ ⋅ (K km s−1 pc−2)−1 | 1.9 × 109 M⊙ | |
| SCO (2−1) | Circumnuclear disk | 29 ± 3 Jy km s−1 |
 |
1.2 × 107 K km s−1 pc2 | |
| M (H2) | αCO = 0.8 M⊙ ⋅ (K km s−1 pc−2)−1 | 5.3 × 107 M⊙ |
| αCO = 4.6 M⊙ ⋅ (K km s−1 pc−2)−1 | 3.1 × 108 M⊙ |
Notes. We estimate the total H2 mass assuming two different conversion factors between the luminosity of the 12CO (2–1) line and the mass of the molecular gas. The lower values of the mass are obtained adopting the typical value for the optically thick gas in ULIRG and AGN (αCO = 0.8 M⊙ ⋅ (K km s−1 pc−2)−1) and the upper limit are given for a Galactic conversion factor (αCO = 4.6 M⊙ ⋅ (K km s−1 pc−2)−1).
