Notes. gij is the ith parameter (1 ≤ i ≤ 3) of the log-normal model distribution of the gas phase j (1 ≤ j ≤4 for CNM to XNM). Parameters pk are adjustedfor obtaining the two-dimensional model of the frequency distribution of the Gaussians in the component central velocity – line-width plane. NO and NM are the actual and model numbers of the Gaussians in different counting bins. Each family has sub-models for NG ≤ 3, 4, 5, 6, or 7.
