Variations of the eccentricity and inclination for orbits with different initial inclinations surviving the integration time of 3.4 × 10⁷ yr. The initial eccentricity is 0.04975 for all orbits. There might be many orbits with different initial semi-major axes for each initial inclination. The orange squares indicate orbits whose libration amplitude (Δσ) is larger than 300° while black crosses indicate those which have never left the tadpole region around L₄ during the integration time (Δσ <  180°).
