a Frequencies and spectroscopic parameters are from the Jet Propulsion Laboratory (JPL) molecular database (Pickett et al. 1998) and the Cologne Database for Molecular Spectroscopy (Müller et al. 2005).
b Gaussian fit.
COng Non-Gaussian profile. The line intensity is obtained by integrating the zero power full width (ZPFW) range. In particular −5, +20 km s−1 for CO (2 – 1) (see Figure A.5). The value has to be considered a lower limit given the presence of absorption features.
ng Non-Gaussian profile. The line intensity is obtained by integrating the ZPFW range.
h1 The detected 2 – 1, J=5/2–3/2, F=3–2 line consists of two hyperfine components with Sμ2 ≤ 6 D2 (Müller et al. 2005) in a 0.8 MHz frequency interval. The line with the highest Sμ2 line is reported (see, e.g., Figures A.1).
h2 The detected 3 – 2, J=7/2–5/2, F=9/2–7/2 line consists of three hyperfine components with Sμ2 ≤ 3 D2 (Müller et al. 2005) in a 0.5 MHz frequency interval. The line with the highest Sμ2 line is reported (see, e.g., Figures A.1).
h3 The detected 3 – 2, F=4–3 line consists of three hyperfine components with Sμ2 ≤ 35 D2 (Müller et al. 2005) in a 0.3 MHz frequency interval. The line with the highest Sμ2 line is reported (see, e.g., Figures A.1).
