Observed and fitted parameters of the H₂O and CO 5-4 lines and prediction for the H₂O line flux.

Notes. The CO fluxes in the HVC and LVC are integrated in the velocity intervals [-30; -7.25] and [-7.25; +11.0], respectively. The H₂O fluxes are derived from a multiple Gaussian fit to the line profile. Intensities are expressed in units of antenna temperature () . ⁽¹⁾ From CSO observations smoothed down to the resolution of the HIFI observations;⁽²⁾ determined from LVG analysis of the CO emission;⁽³⁾ from comparison of LVG-derived N( ) with N(CO), assuming a water OPR of 3 and an abundance H₂ ] = 10^-4.
