Notes. All lines have been fit taking the hyperfine structure into account as explained in Sect. 3.1.1. Cols. 2–5 report the output parameters of the fitting procedure (A × τm = f [ Jν(Tex) − Jν(TBG) ], where f is the filling factor, assumed to be unity, Jν(Tex) and Jν(TBG) are the equivalent Rayleigh-Jeans excitation and background temperatures, respectively, and τm is the opacity of the main group of hyperfine components; Vpeak = peak velocity; Δv = full width at half maximum corrected for hyperfine splitting; τm = opacity of the main group of hyperfine components) for the (1,1) line, and Col. 6 lists the excitation temperature of the transition derived as explained in Sect. 3.1.2. The uncertainties obtained from either the fitting procedure (parameters in Cols. 2–5) or from the propagation of errors (Col. 6) are in parentheses.
The spectrum shows two velocity components (Fig. A.2). Only the fit to the stronger component is shown;
