Distribution of the H₂ 2.122 μm emission in the disc plane. Upper panel: PV diagram of the H₂ 2.122 μm line perpendicular to the direction of the jet axis and in the disc plane. Lower panel: Peak radial velocities with error bars computed from fitting across the PV diagram at the every position with 005 steps. The region from to around position at 0″ corresponds to the bright core of H₂ emission around the jet source.
