Results from thegas kinematics analysis. The left panel shows the Hα velocity map of NGC 5947 shown in Fig. 27. The central panel shows the best-fit model assuming a simple arctan-rotational curve. Finally the right panel shows the residual after subtracting the model to the velocity map. The spaxels not used in the fitting procedure have been masked. Contours indicate different velocity levels, with constant step of 30 km s^-1 in the first two panels, and 10 km s^-1 in the last one.
