Initial mass values and uncertainties for the main-belt asteroids, Trojans and Centaurs in the perturber list. The color code indicates the taxonomic type, the masses from R. S. Park et al. (2021) and uncertainties from D. Farnocchia et al. (2021; SB 441), the set for which we assume 2 ± 1 g cm⁻³, and other sources. Objects of GM > 1 km³s⁻² are labeled. The full list is in available as supplementary information with an excerpt in the Appendix in Table 5.
