The orbital distributions of NEOs from the 3:1 source for three disruption thresholds: q* = 0.005 au (red line), q* = 0.1 au (green line), and q* = 0.2 au (blue line). By increasing the disruption distance in the model, we remove the orbits with high eccentricities, and the eccentricity distribution becomes more peaked near e = 0.5. At the same time, the inclination distribution becomes narrower.
