What is the Astropy Claude Code Skill?

It is a domain-specific enhancement for Claude that provides implementation patterns and best practices for using the Astropy library in Python for astronomical research.

Can this skill help with FITS file headers?

Yes, it provides optimized patterns for reading, writing, and modifying FITS headers, as well as managing multi-extension data units (HDUs).

Does it support coordinate system conversions?

Absolutely. It handles transformations between ICRS, Galactic, FK5, and AltAz frames, including support for observer locations and specific time scales.

How does it manage physical units?

The skill guides Claude to use the astropy.units subpackage, ensuring that physical quantities are handled with their units attached to prevent calculation errors.

Is it useful for cosmological simulations?

Yes, it includes patterns for using built-in cosmological models like Planck18 and WMAP to calculate distances, lookback times, and Hubble parameters.
