Integrated intensities of the strongest transitions of o- and p-H₂O to be targeted by HIFI and PACS, for the eight shock models presented in panels b) and c) of Fig. 5. The o-H₂O and p-H₂O transitions are indicated by circles and squares, respectively. The shock model parameters are abbreviated such that “n4b1.50v28t500”, for example, corresponds to a pre-shock density of 10⁴ cm^-3, a magnetic-field parameter of 1.5, a shock velocity of 28 km s^-1, and an age of 500 years.
