Double-peaked emission observed in the [Ar II], [Ne III], and [FeII] emission lines. Left column: moment 0 map of the lines with aperture positions covering sample pixels with double-peaked emission. Middle column: Spectra of a double-peaked emission line in blue, green, and red for [Ar II], [Ne III], and [Fe II], respectively. 1D Gaussian fits to each velocity component are shown in dashed lines. The estimated radial velocity values of the low- and HV components are indicated. Right column: distribution of the HV component associated with the jet emission. The brightest white-orange regions correspond to the strongest jet emission.
