maguniverse 0.1.4

A Python-based data manager for working with tabulated data from publications of observational surveys of cosmic magnetic fields.

Magnetic Field in the Universe

A Python‑based data manager for working with tabulated data from publications of observational surveys of cosmic magnetic fields. Instead of hosting large data files, this repo gives you the scripts, parsers, and notebooks you need to download, standardize, and compare datasets from the literature (dust polarimetry, Zeeman splitting, Faraday rotation, and more).

---

Goals

• Provide reproducible Python pipelines that turn publication data products into clean, science‑ready tables on your own machine.
• Make it simple to build your data collection and keep it in sync with new survey releases.
• Enable cross‑comparison between magnetic‑field-related quantities from different publications or surveys.
• Serve as a lightweight, community‑maintained magnetic-field-in-the-universe research knowledge base.

Download all the Data You Want In Your Browser

magUniverse now offers browser-based data downloads powered by Pyodide. This eliminates the need for local Python installation or environment setup.

Technical Details

• WebAssembly Python through Pyodide
• Automatic magUniverse installation via Pypi or the latest CI build wheel
• Direct file downloads inside your browser
