Notes. The naming jet is for detection of a high-velocity component to the extended emission (≈ 100 km s−1 from line center), and ext is for detection of extended emission, but at low velocity (< 50 km s−1 from line center). VW Cha has a detection of a high velocity [Ne II] in its spectra, but it is not confirmed in the extended emission.
