Table 1
Best-fit model parameters for the ISM in FCC 167.
| Model | log (M∕M⊙) | Radius R (pc) | Width W (pc) | Height H (pc) | Inclination i (degrees) |
|---|---|---|---|---|---|
| ALMA CO | 7.67 ± 0.06 | 151 ± 62 | 223 ± 12 | 223 ± 8 | 76.3 (fixed) |
| THEMIS MW | 4.70 ± 0.03 | 321 ± 40 | 276 ± 99 | 16.6 ± 6.0 | 77.6 ± 1.8 |
| Silicates | 4.80 ± 0.04 | 285 ± 53 | 217 ± 151 | 13.6 ± 8.2 | 76.3 ± 1.2 |
Notes. Top row corresponds to the molecular ring, where the inclination was kept fixed. Bottom rows correspond to the dust ring geometry. Two different dust mixes were run: a canonical THEMIS MW dust mix and a dust mix with only bare silicate grains. The dust mass, inclination, and the dimensions of the dust ring are free parameters. In all cases, the geometry is defined by Eq. (3).
