SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill automates the critical quality assurance process for astronomical images, ensuring they meet stringent scientific standards before further processing or archival.

Core Features & Use Cases

  • Automated Image Validation: Performs astrometry, flux scale, and source count completeness checks.
  • Diagnostic Reporting: Generates detailed HTML reports with plots for easy review.
  • Use Case: After an imaging run, this Skill automatically verifies that the resulting FITS image is accurately centered, has correct flux calibration, and contains the expected number of sources, flagging any issues for review.

Quick Start

Run the validation skill on the image file '/data/image.fits' to check its quality.

Frequently Asked Questions about Validation Skill

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate astronomical image quality for FITS files?▼

You validate astronomical FITS images by running automated checks on astrometry, flux scale, and source count completeness against reference catalogs. This verifies scientific rigor and data integrity for radio astronomy continuum imaging pipelines.

What quality assurance checks are needed for radio astronomy continuum imaging?▼

Quality assurance for radio astronomy continuum imaging requires validating astrometry to ensure accurate centering, checking flux calibration, and verifying source count completeness against expected values to flag any issues before further processing or archival.

Do I need reference catalogs to check astrometry and flux scale in FITS images?▼

Yes, you need reference catalogs to check astrometry and flux scale in FITS images. The validation process compares your astronomical image against these catalogs to verify accurate centering, correct flux calibration, and expected source counts.

How do I automate QA reporting for FITS image validation?▼

Automate QA reporting for FITS image validation by running a Skill that generates detailed HTML reports with plots. This provides an easy review format after verifying that your astronomical image is accurately centered and correctly calibrated.

What happens if my astronomical FITS image fails source count completeness checks?▼

If your astronomical FITS image fails source count completeness checks, the validation Skill flags the issue for review in a diagnostic HTML report. This indicates the image does not contain the expected number of sources compared to the reference catalog.
