Velocity maps for all seven galaxies in our sample, demonstrating the effect of symmetrisation within the JAM model. The leftmost column shows the observed velocity (V) maps. The V_sym column presents the same velocity maps after applying the symmetrisation procedure used by the JAM model. The V − V_sym column shows the residuals between the observed and symmetrised velocities. The V − V_model column shows the residuals between the observed velocity and the best-fitting JAM model (with a mask of E(B − V) < 0.7). Finally, The V_sym − V_model column shows the residuals between the symmetrised velocity field and the JAM model. Our diagnosis of non-axisymmetric velocity structures consider only features that are also clearly visible in the V_sym − V_model residuals, as these are unaffected by the symmetrisation process.
