The data in the paper can be reproduced executing the jupyter notebook analysis.ipynb
The jupyter notebook should explain the directory structure sufficiently and allow the reader to follow the post-processing.
The notebook is written in python 3 and contains code to produce all figures (but densities of states) in the manuscript and SI. The reference state (nitrogen or ammonia) can be changed by setting the respective flag at the top of the file.
