Asteroid dynamical families: a reliability test for two identification methods

摘要: Since a couple of years the asteroid families are under light renewed interest. This is due to simultaneous improvement techniques proper elements computation and methods classification. Recently, two different cluster analysis (Zappala et al. 1990; Bendjoya 1991) have provided very similar lists families. has brought confidence on reliability new set improved now available (Milani & Knezevic 1992), idea present work test identification by means artificially generated in order gain an insight into their limitations possibly develop strategies for future analyses
