Notes. Statistical parameters of solutions for which clones of (87887) 2000 SS286 and (415992) 2002 AT49 converged at a relative distance of 8 RHill ≃ 4 800 km (all 106 possibilities in our numerical experiment). Tage and δTage is the mean value of the age and its formal uncertainty in kyr. The results are sorted into four cases according to the assumption about the rotation sense of the clones: cosγ1 and cosγ2 are cosines of obliquity of the the clones of the primary and secondary in the pair. P is the fraction of solutions in each of the cases.
