Notes. Entries in the table are molecular transition, rest frequency, total observing time including the two polarizations, final rms in a single spectrometer channel in the vicinity of the line, integrated line intensity (opacity corrected for the HFS fits; see Sect. 2.5.3 of the CLASS user manual: https://www.iram.fr/IRAMFR/GILDAS/doc/pdf/class.pdf), line velocity, and line width. Integrated line intensities have been corrected for the beam efficiency but not for the coupling to the source. Values in parenthesis are 1σ fit uncertainties. (a) The 3σ upper limit integrated over a 2.5−5.5 km s−1 velocity range. An unidentified ~7.5σ feature is detected at 22.902 GHz, which is not present in the Cha-MMS1 spectrum. The opacity of the main NH3 (1,1) hyperfine component implied by the HFS fit is 2.85 ± 0.04.
