Notes. (a) The NH and NH2 frequencies refer to the strongest hyperfine structure component; (b) HIFI consists of 7 different mixer bands and two double sideband spectrometers. All transitions were observed in the upper sideband except NH+; (c) system temperature; (d) the on-source time for each integration.
