Notes. Tentative detections are marked with an asterisk in front of the molecule name. The spectra and their fits are plotted in Figs. A.1 and A.2. (a)13CO was fit with two Gaussians (b) The peak temperature, Tmb, peak, the line width of the spectral lines, Δv, and the vLSR, and the Trms of the data of the spectral lines were determined with a Gaussian fit with the CLASS package of the GILDAS software and the CURVE_FIT module of SCIPY (Virtanen et al. 2020); (c) hyperfine components were detected; (d) the position of the hyperfine transitions is given relative to the strongest transition (Fig. A.1).
