Ortho-NH3 hfs components: normalised high resolution spectra (Δv = 0.13 km s-1) towards W49N in the +39 km s-1 velocity component. Three hfs components are seen at 38.4, 39.4 and 40.0 km s-1. Also shown are the positions and relative intensities of the hfs components and their fitted opacity profiles with a line width of 1.0 km s-1.
