Notes. In the case of non-detections, we indicated the upper limit in the column density with <. For optically thick molecules, we include the optically thin isotopolog that we used to derive the column density of the main isotopolog. The resulting physical parameters, along with their associated uncertainties, are presented. The values of the parameters that were kept fixed are shown without uncertainties. We also present the maximum line opacity of the transitions of each molecule (τmax), and the molecular abundances compared to H2. The transitions of each species used to perform the fits are listed in Table S 2. The isotopic ratios used and the N(H2) used are explained in Sect. 3. aMaximum τ of all the transitions detected in each molecule. bN(H2) = (1.0 ± 0.2) × 1025 cm−2 of the G31.41 core obtained by Mininni et al. (2020). c v0 is the systemic velocity of G31.41 which is 96.5 km s−1 (Beltrán et al. 2018).
