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 −40, +40 km s−1 for CO (2–1), +8, +12 km s−1 for 13CO (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=4–3, F1=3–2 line consists of two hyperfine components with Sμ2 ≤ 8 D2 (Müller et al. 2005) in a 0.05 MHz frequency interval. The line with the highest Sμ2 line is reported (see, e.g., Figures A.2).
h2 The detected 5 – 4 line consists of four hyperfine components with Sμ2 ≤ 38 D2 (Müller et al. 2005) in a 0.0 MHz frequency interval. The line with the highest Sμ2 line is reported (see, e.g., Figures A.2).
h3 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.2).
h4 The detected 3 – 2, J=5/2–3/2, F=7/2–5/2 line consists of two hyperfine components with Sμ2 ≤ 2 D2 (Müller et al. 2005) in a 0.4 MHz frequency interval. The line with the highest Sμ2 line is reported (see, e.g., Figures A.2).
h5 The detected 3 – 2, F=4–3 line consists of three hyperfine components with Sμ2 ≤ 35 D2 (Müller et al. 2005) in a 0.7 MHz frequency interval. The line with the highest Sμ2 line is reported (see, e.g., Figures A.2).
h6 The detected 3 – 2 line consists of 40 hyperfine components with Sμ2 ≤ 312 D2 in a 3 MHz frequency interval. The values are taken from L. Dore in private communication. The line with the highest Sμ2 line is reported (see, e.g., Figures A.2).
