An Algorithm for Coordinate Matching in World Coordinate Solutions
J. Postma, D. A. Leahy
Abstract
Algorithms for point source extraction and catalog-to-image coordinate matching for world coordinate solutions are presented. In particular the coordinate matching algorithm is lightweight, simple to understand, easy to code, and solves orders of magnitude more quickly than existing solutions to this common astrometric problem.
