Evolution of the semi-major axis (top), eccentricity (middle) and mutual inclination with the inner binary (bottom) of the test particles in the ei60 N-body setup. Each colour represents a different test particle that started at a given semi-major axis. The semi-major axis of a particle falls to 0 once ejected from the system. The particle starting with a = 20 au was ejected from the system before the completion of the first orbit of the outer binary.
