Upper panel: maps of Hα Gaussian fit velocities (top left), Hα Gaussian fit dispersion (bottom left) and their respective reconstructed (middle) and residual (data-model) maps (on the right) for IRAS F21453-3511. Lower panel: radial profiles of the kinematic properties, obtained using kinemetry program. The position angle Γ and the flattening q of the best-fit ellipses, as well as the first and the fifth order Fourier terms (respectively, k₁ and k₅) are plotted as a function of the radius.
