Comparison of our collisional model with JWST observations (Burdanov et al. 2025). The SFD for the sum of C- and S-types (green) exhibits a change of slope from shallow to steep (q = −2.66) at approximately 100 m, in agreement with the observed (gray), debiased (blue), and scaled (dash-dotted) SFD from JWST. For reference, we also plot the synthetic SFD of S-types (gray); these S-types are about five times less numerous than C-types and exhibit a change of slope at a smaller size (∼50m).
