Effect of the halo flattening. Physical trajectories and the corresponding Poincaré sections y − vy with plane x = 0 and vx> 0 for the orbits listed in Table 1. The orientation is φ = 90.0, the flattening has been increased with respect to Fig. 3 to be qz = 1.4. The L-orbits, close to disc, with high velocities remain similar. The predictability of orbits with low velocities slightly decreases. The H-orbits with low velocities remain similar. The predictability of orbits with high velocities increases (and the chaos decreases).
