Difference between the morphological PA (PAmorph) and the kinematic PA (PAkin) against the ellipticity of the outermost isophote of the galaxy for the stars (top panel) and the ionised gas (bottom panel). Both kinematic sides of the velocity maps were compared with PAmorph. In each panel, the green filled circles represent the unbarred galaxies, blue diamonds are weakly barred galaxies, and violet squares correspond to barred galaxies. For early-type galaxies we use empty circles. Labels indicate the 3σ outliers. Dashed lines represent the projection effect of a morpho-kinematic misalignment of 60° measured in the plane of the galaxy. In each panel, the grey area represents the 2σ dispersion of the sample.
