Position-velocity diagrams of the ionised gas. The left panel shows the pv diagram along the major axis (θ = 135°) of the [NII]-Hα triplet, whereas the right panel shows the pv diagram of the [OIII] line. The contours denote the (2, 4, 8, 16, 21)σ level. The dashed black horizontal line corresponds to the Hα and [OIII] systemic velocity. The cyan line corresponds to the stellar rotation curve. The inset shows the velocity field of Hα, overlaid with the radio continuum (pink contours) and the slice from which the pv is extracted (black hatched area). The arrows indicate kinematically anomalous features.
