Continuum-subtracted position velocity (PV) maps of [O i], [S ii],  and [N ii]  lines observed in the X-shooter spectrum. The PV are oriented along the jet, with a PA = 162°. Contours start at 3σ and are drawn at steps of 3σ with the exception of [S ii]  6731 Å  where the contours are drawn in steps of 6σ. Radial velocities have been corrected for the source systemic velocity of +8 km s^-1. The main peaks are labeled following the nomenclature of Fig. 1. The HVC and LVC are also indicated.
