A messy GitHub repository for my paper measuring ion temperatures at the polar coronal hole boundary region observed by Hinode/EIS and SOHO/SUMER. Some Jupyter notebooks use my naive Python scripts. The HTML exports of the Jupyter notebooks are available in the ipynb_html directory.
Links to the Jupyter notebooks for each Figure (Recommend to open these notebooks in nbviewer to enable the internal hyperlinks in notebooks):
