Spectra around the H₂O lines in ESO 320-G030 observed with Herschel/PACS and ALMA (lower-right panel), along with Gaussian fits to the lines (blue curves). In all panels, the plotted wavelength range corresponds to a velocity range of ±800 km s⁻¹. The adopted baselines are shown with dashed lines. The vertical dotted lines indicate the expected central position of the lines by using z = 0.010266, which is derived from the Gaussian fit to the H₂O448 line observed with ALMA. The Herschel lines are sorted by the lower-level energy (E_l) of the transition, which is also indicated in each panel. The species responsible for other lines in the spectra are also indicated (see also Appendix A).
