Nesvorny HCM Asteroid Families

This data set contains asteroid dynamical family memberships for 122 families calculated from synthetic proper elements, including high-inclination families. These families were calculated by David Nesvorny (Nesvorny et al. 2015) using his code based on the Hierarchical Clustering Method (HCM) described in Zappala et al. (1990, 1994). The input synthetic proper elements for 384,337 numbered asteroids were calculated by Knezevic and Milani.
