numba_extinction

Numba-accelerated implementation of the extinction package.

This package rewrites and extends the functionality of extinction.py using Numba for performance. It reproduces the original extinction curves (albeit with some ~1e-15 differences due to floating-point arithmetic).

An equivalent implementation of the UV-to-IR extinction curve by Gordon et al. (2023) is included and validated against dust_extinction for consistency.

Please check out dust_extinction too! It is much more fleshed-out and feature complete. This package was developed for personal purposes before I discovered dust_extinction and is not meant to be a replacement.

Installation

You can install numba_extinction from PyPI or in editable mode for development.

Install from source
