Test particles were integrated with initial conditions (Section 2.2) to determine the placement of the planetesimal disk. Final vs. initial semimajor axes of all test particles are shown after integration for three million years. Planet initial positions are shown for this nonchaotic simulation. Test particles (black dots) were almost entirely removed inward of 20 au, and thus this was chosen for the inner edge of the disk. Higher density is shown as darker purple.
