Saturated reduced low‐resolution spectrum for the slit orientation ﹩\psi _{s}=144^{\circ }﹩, showing the trail of the jet. The color triangle corresponds to the intensity 5%. The signal along the jet is up to 25% of maximum intensity, yet it is important to realize that the spectrum in this region is crowded, so that some line confusion is probable. Higher resolution and better S/N spectroscopy of this region is required.
