Position-velocity diagrams at azimuthal angles (θ) of (0, 30, 60, 90, 120, 150) degrees with respect to the major axis in the plane of the sky. The data cube was spectrally smoothed with a 7 km s⁻¹ Hanning kernel. The solid contour levels denote the (4, 16, 64, 256, 1024)σ level, where σ = 0.03 mJy beam⁻¹. The dashed grey contours refers to the −4σ level. The dashed black horizontal line corresponds to the systemic velocity, while the dash-dotted black vertical line denotes the centre of the galaxy. The insets shows the moment 2 map and the slice along which the pv is extracted. The letters A and B provide the orientation in the main panels.
