DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : This data set contains the high-inclination asteroid families of Gil-Hutton (2006). A data set of 3652 high-inclination numbered asteroids was analyzed to search for dynamical families. The basic data set was the list of 3697 asteroid synthetic proper elements taken from the Asteroid Dynamic Site, March 2005 version; Knezevic and Milani (2000). For this analysis, only asteroids with sine of proper inclination greater than 0.3 were used. Three data files are included. Families.tab contains a list of the members of each of the thirteen families, along with their proper elements. Clumps.tab contains a list of the members of each of the 22 clumps, along with their proper elements. Summary.tab lists the families and clumps, with the number of the least-numbered member, the proper elements of the least-numbered member, and the range of proper elements for each family and clump. A cluster of objects in proper element space is considered a nominal family (clusters related to the breakup of an asteroid) or a clump (clusters not necessarily related to breakup events) if they have a number of members larger or smaller than a limiting number, which is defined as 2.5 times the minimum number of objects for a cluster to be considered significant (Zappala et al. 1995).
