HK and JH spectrum of knot C14. The flux scale in HK (black) is normalised to the peak flux density of the H2 1–0 S(1) emission, and the JH spectrum (red) has been scaled such that line H2 1–0 S(7) exhibits the same normalised flux in the JH and HK spectra. The identified molecular hydrogen ro-vibrational lines are indicated.
