Tools to recover expectionally precise rotation curves from spatially resolved spectra.
Project description
eddy - Extracting Disk DYnamics
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, If you want to run the Gaussian Process method you will also need celerite which can be easily installed if you follow their installation guide.
If things have installed correctly you should be able to run the Jupyter Notebooks with no errors. If something goes wrong, please open an issue.
Useage
For guides on how to use eddy you will find extensive examples in the documents. We shamelessly recommend bettermoments to make the moment maps required for the fitting.
