Physical trajectories and the corresponding Poincaré sections y − v_y with plane x = 0 and v_x> 0 for the orbits listed in Table 1. The orientation is φ = 0.0, the flattening is q_z = 1.25. The asymptotic Lyapunov exponent λ characterises the chaos intensity. The predictability index h characterises the predictability. There are spherical-like and tube-like orbits in the physical space, with regular behaviours at the highest velocities (LF2, HF2, LC2, and HC2).
