Table 4
Column densities and masses of N2H+ in G351.77 protocluster.
| Ncol | <N(N2H+)> × 1013 (cm−2) | M(N2H+) × 10−6 (M⊙) |
|---|---|---|
| NB(N2H+) | 1.49 ± 0.41 | 1.77 ± 0.49 |
| NR(N2H+) | 1.79 ± 0.49 | 2.19 ± 0.61 |
| NT(N2H+) | 2.28 ± 0.56 | 3.96 ± 0.78 |
Notes. Averages of N2H+ column density estimations and total N2H+ masses. NB, NR, and NT correspond to the blue velocity component, the red velocity component, and NB + NR, respectively. The errors are estimated based on the distribution of the percentage errors in column densities, to prevent underestimations.
