Notes. The planetesimals in the ring are generated according to a Gaussian distribution. Each planetesimal has the same mass, and the numbers in the disk and the ring are listed. The initial masses of the planets, as well as the initial eccentricities and inclinations of the planets and planetesimals, remain the same as the ones described in Section 2 and are not listed again.
