Does it support World Coordinate System (WCS) transformations?

Yes, it includes comprehensive guidance for mapping pixel coordinates to sky coordinates (and vice versa) using WCS headers and SIP distortions.

Can this skill help with telescope image analysis?

Yes, it provides specific patterns for FITS I/O, background subtraction, source detection, and aperture photometry using libraries like Astropy and Photutils.

How does it handle physical units?

The skill leverages the astropy.units module to ensure all calculations are dimensionally consistent, providing automatic conversions and spectral equivalencies for frequency, wavelength, and energy.

Is it useful for catalog cross-matching?

Absolutely. It provides efficient patterns for matching celestial coordinates across different catalogs and reference frames like ICRS, Galactic, and FK5.

What is the Astropy Fundamentals skill used for?

This skill is used to work with astronomical data formats, perform celestial coordinate transformations, handle physical units, and manage precise astronomical time scales within the Claude environment.
