Line fluxes of isotopologues of H2O in the observed HIFI range.

λ(μm) Transition Isotope Line fluxes (× 10-17 W m-2)

269.272 111−000 16 18.2 8.3 a a a
270.774 111−000 17 9.2 3.6 1.1 0.6 1.0

273.626 312−303 18 <0.8 <0.6 <0.4 <0.3 <0.4

Notes. “a” indicates that the transition is not observed. The fluxes for HO indicate the upper limit of the detection and as such can be regarded as an estimated uncertainty of the calculated line fluxes.
