Snapshots (xy and xz) of the bar (top two rows) and the structure assembled from the orbits trapped into the bar in the time interval t = 300 − 400 (bottom two rows) at t = 500. The first column shows all orbits under consideration. Structures assembled from orbits that increased and decreased their resonant angle θ_z − θ_R are displayed in the second and fifth columns, respectively. The third and forth columns show orbits in the vILR and passing through it, respectively.
