NESVORNY HCM ASTEROID FAMILIES V2.0

This data set contains asteroid dynamical family memberships for 64 families calculated from analytic proper elements, and 79 families calculated from synthetic proper elements, including high-inclination families. These families were calculated by David Nesvorny using his code based on the Hierarchical Clustering Method (HCM) described in Zappala et al. (1990, 1994). The input analytic proper elements for 401,408 numbered and unnumbered asteroids were calculated by Milani and Knezevic. The input synthetic proper elements for 302,212 numbered asteroids were calculated by Knezevic.
