Astronomical Catalog Cross-Referencing Complex Query

astronomy spatial indexing catalog matching geospatial
Prompt
Develop a high-performance SQL query that cross-references multiple astronomical catalogs (Gaia, SDSS, 2MASS) with precision matching criteria. Implement a sophisticated spatial indexing approach using PostgreSQL's PostGIS extension, handling coordinate transformations, managing stellar proper motion corrections, and generating a unified catalog with uncertainty metrics. Include edge case handling for rare astronomical objects and performance optimization strategies.
