# Astropy

Handle units, coordinates and FITS files without fighting them

## What this does

Astronomy data comes with its own units, coordinate frames, time systems and file formats, and getting them right is most of the work. This helps you write and fix Python that handles all of that. Reach for it when you are building or debugging an analysis on astronomical data.

### Top 3 things it does for you

- Work with astronomical units and quantities
- Read and write FITS files
- Convert between coordinate and time systems

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Astropy

Covers the core Python library for astronomy and astrophysics work: units and quantities, coordinates, FITS input and output, tables, time systems, WCS and cosmology.

Use it when implementing or debugging astronomical data analysis code that needs Astropy APIs.

## Questions

### Is Astropy safe to install?

AIR scanned this exact version of Astropy and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit c8c5f9dc5640, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/astropy.

### How do I install Astropy?

Open https://airmarket.ai/app/astropy on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/k-dense-ai/scientific-agent-skills/tree/c8c5f9dc5640d0bd173e32d6192172443c31db4b/skills/astropy. Install from that link, not the branch.
