## What Is It?

`eddy` is a suite of Python tools to recover precise velocity profiles of protoplanetary disks from Doppler shifted line emission. `eddy` makes fitting of first moment maps and the inference of a rotation velocity from an annulus of spectra a breeze.

## Installation

The most simple method is with `pip`,

```
pip install astro-eddy
```

The only real dependencies for this are `numpy`, `scipy`, `matplotlib`, and [`emcee`](https://github.com/dfm/emcee), If you want to run the Gaussian Process method you will also need [`celerite`](https://github.com/dfm/celerite) which can be easily installed if you follow their [installation guide](https://celerite.readthedocs.io/en/stable/python/install/).

If things have installed correctly you should be able to run the [Jupyter Notebooks](https://github.com/richteague/eddy/tree/master/docs/tutorials) with no errors. If something goes wrong, please [open an issue](https://github.com/richteague/eddy/issues/new).

## Useage

For guides on how to use `eddy` you will find extensive examples in the [documents](https://github.com/richteague/eddy/tree/master/docs). We shamelessly recommend [bettermoments](https://github.com/richteague/bettermoments) to make the moment maps required for the fitting.

## Citations

If you use `eddy` as part of your research, please cite the [JOSS article](http://joss.theoj.org/papers/10.21105/joss.01220):
