Document Collection Contents The document collection contains documentation files, where available, for this bundle. All document files will have an accompanying label file to describe content and structure. Label files have the same name as the main document file, with an extension of ".xml". list_of_new_families_2024.txt - List of new families - The new families are listed separately for the inner belt, middle belt, pristine zone, outer belt, and high inclinations. Each family is identified by the number and/or name of a reference asteroid - usually the brightest member. For each family, the list gives the HCM cutoff (m/s) and the number of family members listed in the file. hcluster.c - Updated HCM families program for synthetic proper elements - Hierarchical Clustering Method (HCM) code of David Nesvorny, which was used to generate the 153 new asteroid families from synthetic proper elements hcluster_syn_c.asc - HCM FAMILIES PROGRAM FOR SYNTHETIC PROPER ELEMENTS used for previous data from 2015 - Hierarchical Clustering Method (HCM) code of David Nesvorny, which was used to generate the 119 asteroid families from synthetic proper elements of this data set. To use the code, the filename must be changed from 'hcluster_syn_c.asc' to 'hcluster_syn.c'. nrutil_c.asc - MEMORY ALLOCATION FUNCTIONS FOR HCM CODE - This file includes memory allocation functions and is used, along with nrutil.h, in compiling hcluster_syn.c. To use it, rename to nrutil.c. nrutil_h.asc - MEMORY ALLOCATION FUNCTIONS HEADER - This file contains the header for nrutil.c and is used with it in compiling the HCM code hcluster_syn.c. To use, rename to nrutil.h. numb_syn.asc - KNEZEVIC AND MILANI SYNTHETIC PROPER ELEMENTS OF NUMBERED ASTEROIDS - This file contains synthetic proper elements of numbered asteroids calculated by Knezevic and Milani using the method described in Knezevic et al. (2002). This file was the input to the Nesvorny HCM program hcluster_syn.c in producing the families from synthetic proper elements in this data set. In order to be used as input to hcluster_syn.c, this file must be renamed from 'numb_syn.asc' to 'numb.syn'. bundle_description.txt - Bundle description for the ast.nesvorny.families bundle - A document describing the content and structure of the bundle. ref.txt - Reference List - The reference list for the bundle. host_VARGBTEL_description.txt - Description of VARIOUS GROUND-BASED TELESCOPES - This is an automatically generated document that contains the description of the VARIOUS GROUND-BASED TELESCOPES instrument host. instrument_VARGBDET_description.txt - Description of VARIOUS GROUND-BASED DETECTORS - This is an automatically generated document that contains the description of the VARIOUS GROUND-BASED DETECTORS instrument. AA_Document_Index.txt - Document Index - The file you are reading. collection_ast.nesvorny.families_document_inventory.csv - Collection Inventory - An inventory of document products in this collection.
