Distributions of the physical parameters of NH₃ fragments. (a) Histogram of kinetic temperatures T_k. (b) Histogram of total velocity dispersions σ_υ (including bulk motions and using the thermal component of the entirety of the molecular gas). (c) Histogram of deconvolved radii of NH₃ fragments R_dec. (d) Histogram of NH₃ column density N(NH₃). (e) Histogram of nonthermal velocity dispersion with bulk motions σ_υ,NT. (f) Histogram of nonthermal velocity dispersion without bulk motions σ_υ,ng.
