DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : Proper elements of asteroids are derived from the osculating orbital elements by correcting for the perturbations of the major planets to arrive at elements which are stable over time periods comparable to the age of the solar system. The purpose of computing proper elements is twofold, to detect asteroid 'families', which are dynamically related groupings of asteroids potentially of common origin, and to understand the dynamical structure of the asteroid belt. This data set includes the asteroid proper elements collected by Andrea Milani in version 7.0 of his proper elements collection. This entire collection, including proper elements and the software and input data for deriving them is distributed by Milani to the scientific community via anonymous ftp. The proper elements alone are extracted from the full collection and are archived here. All these data have to be considered in the public domain; of course the users are committed to quote the source of the data they use for any scientific purpose. Commercial utilization, as well as incorporation into commercial products, is not authorized. The following proper element sets are included here. Milani, A., and Z. Knezevic 1994.
