Scientific paper

High-velocity wing emission in CS and NH3 spectra towards the bipolar flow source NGC 2071 are compared. Column densities of CS and NH3 in the high-velocity wing emission are comparable, which means that CS is overabundant relative to NH3 by one to two orders of magnitude. The large enhancement of CS may be caused by an interstellar shock wave generated by the high-velocity outflow from the central infrared source(s).
