Cumulative distributions of the semimajor axis N(≤a) of >100 km asteroids classified as CM-like, CI/IDP-like (including B types with the geometric albedo of p_v < 0.1), and S-type. Vertical dotted lines mark major mean-motion resonances with Jupiter. CM-like objects exhibit an approximately symmetric distribution, whereas CIlike objects show a notably asymmetric distribution.
