Two examples of LTE fit of the CO isotopologues lines. In the titles, Tex is expressed in Kelvin, N in cm−2, ΔV in km s−1, and σV in km s−1. The plain lines show the data, and the dotted ones show the fit results. Values in red indicate estimations whose relative precision is larger than 20%. The associated lines of sight can be localized in Fig. 1 (see red crosses).
