Velocity maps of J1433+0227 associated with CO(4−3) emission detected at > 3σ_{40 km s⁻¹} significance in the original (a) and high-resolution (b) maps, in which σ_{40 km s⁻¹} = 0.43 mJy beam⁻¹ and 0.71 mJy beam⁻¹, respectively. ALMA beams are shown by the grey ellipses. Panel c: velocity map for the best-fit BAROLO model of a rotating disk. Black line indicates the major kinematic axis of the model. Velocity residuals are shown in panel d. Panels e–g: velocity dispersion maps associated with the high-resolution ALMA data and the best-fit BAROLO model, and the dispersion residual map. Position-velocity diagram associated with the high-resolution datacube along major (h) and minor (i) kinematic axes are also shown. Top labels indicate the associated position angles (measured anti-clockwise from north). Blue contours refer to the [2,3,4,5,6,8, …]σ_{40 km s⁻¹} significance.
