What problem does it solve?
This Skill automates the crucial process of matching detected astronomical sources in images with known cataloged sources, enabling source identification, astrometry correction, and flux scale validation.
Core Features & Use Cases
- Source Matching: Compares detected sources against reference catalogs (NVSS, FIRST, RACS).
- Astrometry Correction: Corrects image positions based on matched catalog sources.
- Flux Scale Correction: Adjusts detected source fluxes to match catalog values.
- Use Case: After imaging a region of the sky, use this Skill to identify which detected radio sources correspond to known cataloged objects, and to correct any positional or flux discrepancies.
Quick Start
Use the crossmatch skill to match detected sources in '/data/image.fits' against the NVSS catalog.
