Notes. Columns correspond to the line ratios measured directly from the data, the Gaussian fit of the lines, the ratio of the best-fit model described in Sect. 3.4, and also the best-fit model ratio but when assuming a Gaussian with a fixed FWHM of 600 km s−1 for all the lines. For non-detections we report 1σ upper limits.
