`brutus` is a Python package for Bayesian inference of stellar properties, distances, and extinctions from photometry. It supports individual star fitting, cluster analysis, and 3D dust mapping.

**Documentation**: [brutus.readthedocs.io](https://brutus.readthedocs.io)

## Installation

```bash
pip install astro-brutus
```

Requires Python 3.9+ on Linux, macOS, or Windows with WSL.

**Windows users**: Due to the `healpy` dependency, brutus requires WSL (Windows Subsystem for Linux) on Windows.

### Development Install

```bash
git clone https://github.com/joshspeagle/brutus.git
cd brutus
pip install -e ".[dev]"
```

## Data Files

Download required stellar models and dust maps:

```python
from brutus import fetch_grids, fetch_isos, fetch_dustmaps

fetch_grids()      # MIST stellar grids
fetch_isos()       # MIST isochrones
fetch_dustmaps()   # 3D dust maps
```

Data files are also available from the [Harvard Dataverse](https://dataverse.harvard.edu/dataverse/astro-brutus).
