Distributions of initial and final orbital elements for surviving comets. Upper panels: eccentricity vs. semi-major axis; lower panels: inclination vs. semi-major axis; left panels: periods below 20 yr; right panels: periods above 20 yr. Red dots show initial orbits. For the final orbits, sky-blue dots indicate T_J < 2, dark blue dots indicate 2 < T_J < 3, and green dots indicate T_J > 3.
