Maximum eccentricity reached by either orbit within 10⁷ yr of evolution depending on the initial orbital elements. Black solid circles depict unstable cases (e_max > 1, 44% of the cases). These results were obtained by running N-body simulations starting from 1000 solutions of the orbital fit. Configurations where orbits are crossing or almost crossing are always unstable. Orbits with relative inclination between 40 and 130 degrees are locked in a Kozai resonance, and may experience high eccentricity variations without compromising the stability of the system.
