Distribution of the difference of the longitude of the ascending node (﹩{\rm{\Delta }}{\rm{\Omega }}﹩) of colliding bodies just before the collision in models N16e-1.5i-3.6 (top) and N16e-1.5i-0.5 (bottom). The total number of collisions is 203 in model N16e-1.5i-3.6 and 245 in model N16e-1.5i-0.5. The mean and variance of ﹩{\rm{\Delta }}{\rm{\Omega }}﹩ are 184° ± 62.°1 in model N16e-1.5i-3.6 and 166° ± 117° in model N16e-1.5i-0.5.
