Precovery

Precovery provides the tooling to search through point source catalogs for observations of moving objects. This is used for arc extension of discovery candidates, as well as already confirmed objects. The implementation is sensitive to singleton observations and does not rely on tracklets.

The precovery package provides tooling to:

• Index source-extracted catalogs into a database designed for fast positional queries
• Search for precovery observations for arbitrary orbital state vectors
