Total column densities and masses in G351.77 protocluster.

N_col	<N_tot> × 10²³ (cm⁻²)	M_tot (M_⊙)
N_tot,B	0.89 ± 0.24	740 ± 205
N_tot,R	1.08 ± 0.29	917 ± 253
N_tot,T	1.370 ± 0.38	1657 ± 326

Notes. Averages of total column density estimations and total masses derived from the N₂H⁺ emission. N_tot,B, N_tot,R, and N_tot,T correspond to the blue velocity component, the red velocity component, and N_tot,B + N_tot,R, respectively.
