Low-resolution position-velocity diagrams at azimuthal angles (θ) of (0, 30, 60, 90, 120, 150) for the data and the best-fit model derived by 3D-Barolo fitting the approaching and receding side of the galaxy simultaneously. Both the data and the model cube were Hanning-smoothed at 7 km s⁻¹. For each panel, the background grey-scale image is the slice extracted from the data cube. Solid contour levels are denoting the (4, 16, 64, 256, 1024)σ. The coloured lines refer to the model, the green curves to the data. 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 0-offset. 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.
