^3DBAROLO dynamical model of the ionised gas disc obtained by fitting the Hα data cube. Left panel: rotation curve (green symbols) and velocity dispersion (blue symbols) corrected for beam smearing, as a function of the radius obtained from the best-fit disc model. Right panel: position–velocity diagram along the kinematic major axis, PA = 210 deg. Red contours and yellow filled circles represent the disc model, blue contours represent the data. Contours are drawn at (1, 2, 4, 8, 16, 32, 64)σ.
