NESVORNY HCM ASTEROID FAMILIES V1.0

This data set contains asteroid dynamical family memberships for 55 families, calculated by David Nesvorny using his code based on the Hierarchical Clustering Method (HCM) described in Zappala et al. (1990, 1994). The input proper elements for 293,368 asteroids were calculated by Milani and Knezevic and are restricted to low-inclination asteroids.
