Centroid velocity (top) and velocity dispersion (bottom) of the narrow-red component. The colour scales used here are different from the ones used in the previous figures, with a smaller range chosen to highlight the kinematic features. The panels on the right show the velocity and dispersion of the elongated red-shifted feature. The solid black or solid white contour shows the boundary of the coherent core from singlecomponent fits. The beam and scale bar are shown in the bottom left and the bottom right corners, respectively.
