eddy - Extracting Disk DYnamics
eddy is a suite of Python tools to recover precise rotation 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, emcee, at least v3.0 or higher if you want the fancy progress bar, and corner. 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.
In brief, fit_annulus contains the functionality to infer the rotation profile from an annulus of Doppler shifted spectra, as discussed in Teague et al. (2018a,b). Functions to fit the rotation map (we shameless recommend bettermoments to make these), including a flared surface geometry can be found in fit_cube. This also contains the functionality to deproject images using the geometrical properties of the best fit model.
