AsteroidFamiliesPortal

This page allows to employ the Hierarchical Clustering Method (HCM) to generate a list of potential members of an asteroid family. To performe this action one should select a family from the drop list, and click button called 'Generate'. In this case the list of family members is produced for the nominal cut-off distance.
Advanced options allows to define some additional parameters. In the fields Ast id and Cut-off a number of an asteroid around which the HCM should perform a search, and a distance threshold in m/s should be entered, respectively..
It is also possible to generate membership at different cut-offs. In this case Multiple box should be checked, and the other fields below should be filled. For additional instructions move the mouse over the corresponding field.
IMPORTANT: Please note that the HCM algorithm available here may not use the latest input catalog of asteroid proper elements!
