digest2 is a fast, short-arc orbit classifier for small solar system bodies writen in C.
The code provides a score, which represents a pseudo-probability that a tracklet (set of several
astrometric positions of the same object within a night) belongs to a given solar system orbit type.
digest2 is primarily used as a classifier for Near-Earth Object (NEO) candidates, to identify those
to be prioritized for rapid follow-up observation.
The functionality and componnts of the code are described in details in: Keys, S., Veres, P., Payne, M.J. et al., 2019. The digest2 NEO Classification Code. Publications of the Astronomical Society of the Pacific, 131:064501 (22pp)
and in Veres, P., Cloete, R., Weryk, R. et al, (in prep). Improvement of digest2 NEO Classification Code
utilizing the Astrometry Data Exchange Standard.
the original repository of the code was in https://bitbucket.org/mpcdev/digest2/src/master/
However, the new repository will be available at https://github.com/Smithsonian/digest2
The new repository consists of three directories:
1) population (contains the population model, configuration file with observatory codes and uncertaities and archive with previous config and population model. Also contains make_population directory with the instruction how to construct the population csv file) 2) archive (previous versions of digest2 code) 3) digest2 (the main and current repo with the source code, with the instructions and readme files)
