DMTN-031: Pessimistic Pattern Matching for LSST

Dataset ·

The current reference catalog matcher used by LSST for astrometry has been found to not be adequately robust and fails to find matches on several current datasets. This document describes a potential replacement algorithm, and compares its performance with the current implementation.
