Notes. Transitions with predicted intensities above 40 mJy beam−1 km s−1 shown in Fig. A.1 with the fitted column density and excitation temperature described in Sect. 3. The frequencies appear in MHz and the upper energies in K. * Transitions separated by less than 1 km s−1 (the FWHM of lines towards IRAS16293B) that consequently appear blended in Fig. A.1.
