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:
- 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)
- archive (previous versions of digest2 code)
- digest2 (the main and current repo with the source code, with the instructions and readme files)
