Astropy Astrophysics Toolkit

关于

Equips Claude with specialized knowledge for performing complex astronomical tasks using the Astropy library. This skill enables precise handling of celestial coordinates, physical units with dimensional consistency, and high-precision time conversions across various scales. It provides implementation patterns for reading and writing FITS files, managing large astronomical catalogs through unit-aware tables, and calculating cosmological distances and ages. Ideal for researchers and data scientists, it ensures scientific accuracy by following best practices for image processing, world coordinate systems (WCS), and physical constant management.

主要功能

• FITS file manipulation including header access and multi-extension handling
• Cosmological model calculations for distances, ages, and redshift parameters
• Celestial coordinate transformations across ICRS, Galactic, and AltAz frames
• High-precision time handling for multiple scales including UTC, TAI, and TDB
• Unit-aware physical quantity calculations with automatic dimensional consistency
• 2,066 GitHub stars

使用场景

• Cross-matching celestial catalogs and performing unit-safe tabular data operations
• Processing and analyzing astronomical images and spectral data in FITS format
• Calculating cosmological parameters and lookback times for deep-space observations
