Notes.The rest wavelength λ0 (μm) of the transition is indicated. The percentages between brackets indicate the uncertainty on Fint, which includes both the fitting uncertainty and the PACS absolute flux calibration uncertainty of 20%.
(*)
Line strengths flagged for potential line blends (see Sect. 2.2.1). Transitions that might cause the line blend are mentioned immediately below the flagged transition.
(a)
Transition detected in an emission doublet. The given value is the sum of the line strengths of both emission lines in the doublet.
(b)
The selection of H2O vapor emission lines based on which we have derived the H2O vapor abundance (see Sect. 4.2.3).
