Table 1
Masses of the structural components of the Vela C molecular cloud, separated by getsf in the surface density images with different angular resolutions.
| Resolution | Sources | Filaments | Background | Total |
|---|---|---|---|---|
| (″) | MS (Μ⊙) | MF (Μ⊙) | MB (M⊙) | MC (M⊙) |
| 8.5 | 6.3 × 103 | 3.0 × 104 | 5.3 × 104 | 9.0 × 104 |
| 11.7 | 2.2 × 103 | 2.5 × 104 | 4.6 × 104 | 7.3 × 104 |
| 18.2 | 2.4 × 103 | 2.6 × 104 | 4.4 × 104 | 7.2 × 104 |
| 24.9 | – | – | – | 7.2 × 104 |
| 36.3 | – | – | – | 7.2 × 104 |
Notes. The value of MS at 8.5″ is likely significantly overestimated because it includes the protostellar sources with strong temperature gradients. The values of MB and MC are given after subtracting the global background 
of the image (or 3.7 × 104 M⊙), taken from the lower left corner of the image in Fig. 1.
