Exorings

UPDATE: code is updated to run in Python 3, and includes exorings3 which is a Python 3 version of the original exorings which runs under Python 2.7.

These are Python tools for displaying and fitting giant extrasolar planet ring systems, as detailed in Kenworthy and Mamajek (2015).

If you need a python 2.7 environment to run the original disk_sim.py, you can set up a conda environment with the appropriate Python modules installed:

conda create --name exo27 -c conda-forge python=2.7 matplotlib numpy scipy astropy
conda activate exo27

then you can copy this repo and run the interactive ring fitter:

git clone https://github.com/mkenworthy/exorings.git
cd exorings/
python disk_sim.py -s 33000. -r 54220.65.try9.33kms.fits -d 54220.65.try9.33kms.fits -o 54220.65.try10.33kms.fits

Explanations on how to use the exorings interface are on the Quick Start page, along with all documentation and discussion on the Exorings wiki.
