SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill streamlines the process of visualizing astronomical data, enabling quick-look analysis, the generation of essential moment maps, and efficient conversion to optimized formats for faster viewing.

Core Features & Use Cases

  • CARTA Integration: Seamlessly use CARTA for interactive visualization of astronomical images and cubes.
  • Data Conversion: Convert FITS files to the HDF5 IDIA format for significantly faster loading and interactive performance.
  • Moment Map Generation: Automatically compute and save moment maps (integrated intensity, velocity, dispersion) from spectral cubes.
  • Preview Generation: Create quick PNG previews of astronomical images for rapid assessment.
  • Use Case: After an imaging run produces a FITS file, this Skill can automatically convert it to HDF5 IDIA, generate moment maps if it's a cube, and create a PNG preview, all ready for review in CARTA or as standalone files.

Quick Start

Use the visualization skill to generate a PNG preview of the image file '/data/image.fits'.
