Notes. The ALMA and APEX lines reported are from UK24, unless otherwise specified. All HIFI lines listed are from our Herschel/HIFI spectral survey of IRAS 15194-5115 (see Sect. 3.3.3). The Yebes 40 m J = 1-0 line and all IRAM 30 m lines are from Massalkhi et al. (2024). For the ALMA (and ACA) lines, the integrated intensity values reported are in units of Jy km s−1 and are calculated using spectra extracted from apertures large enough to encompass all detected line emission. For all other SD observations (APEX, IRAM, Yebes, OSO, HIFI), the integrated intensities are given in units of K km s−1, in the main beam (TMB) temperature scale. The relevant beam size ranges and main beam efficiencies for the different telescopes are described in Sect. 3.3, and the individual beam sizes at each transition frequency are indicated in Fig. 1 and Figs. C.1–C.3 alongside the corresponding line spectra. (a) Woods et al. (2003); (b) Danilovich et al.
