Notes. vlsr and Δv1/2 refer to the velocity centroids and FWHM of the Gaussian components fitted for 13CO. The fit assumes a Tex = 15 K and source size of 3″ (see Sect. 3.2 for details). Despite not being a fitted parameter (see Sect. 3.2.2), the peak flux density of the J = 1−0 transition of all isotopologues used in this analysis is also tabulated.
