Notes. For each line we indicate the corresponding upper energy level and rest frequency, together with the measured line peak intensity, line integrated intensity, and the velocity range used to compute this latter.

^(†)

For o-H₂O, the energies are relative to that of the lowest ortho level (J_{K_a,K_c} = 1_0,1), since o-H₂O and p-H₂O behave as different species.
