Difference between the morphological PA (PA_morph) and kinematic PA (PA_kin) against the total stellar mass for the stellar (top) and the ionised gas (middle), as well as the difference between the stellar and ionised-gas kinematic PA (bottom). Both kinematic sides of the velocity maps were compared with PA_morph (top panels) and between each component (bottom panel). In each panel, the green-filled circles represent unbarred galaxies, blue diamonds are weakly barred galaxies and violet squares correspond to barred galaxies. For early-type galaxies we use open circles. Dashed lines represent the 2σ dispersion of the sample. Labels indicate the 3σ outliers. Error bars are determined from Monte Carlo simulations.
