Notes. Listed are the asteroid name and number, taxonomic type (‘Tax.’), effective diameter of the system (‘Deff’, based off of an equal-volume sphere, except for Eurybates, where it is areal equivalent), uncertainty on the diameter (σD), rotation period (‘P’), Dynamical class (‘Dyn.’), and Family. The uncertainties on the diameter estimates are formal in most cases, and may be subject to additional systematic errors. References are as follows: (1)Mahlke et al. (2022), (2)Berthier et al.
