Notes.(*) Relative intensity values for hyperfine CN transitions obtained from Hily-Blant et al. (2017) and references therein.(**) Integrated flux values and their uncertainties for the CN lines calculated from the emission spectra in Fig. 1, and in the same way for CO isotopologs from Fig. B.1 (a) Value in CDMS catalog is 340.2477700 for both; new value from Teague & Loomis (2020). (b) Value in CDMS catalog is 340.0354080 for both; new value from Teague & Loomis (2020).
