Notes. Some lines are affected by strong noise that increases the errors in the Gaussian fittings.

(a)

The first six H2O lines were detected in absorption with PACS, and we show the energy of their lower level. The last six lines were detected with SPIRE in emission, so we show the energy of their upper level.

(b)

Due to the low velocity resolution of the SPIRE instrument ∼250–360 km s−1, these values are very uncertain and we do not consider them in our discussion.
