Description

Contains the data (spectra and Fermi splittings) required to produce the figures in https://doi.org/10.1063/5.0056829. Also includes a Python script that applies the intensity correction factors (Eq. (13) in the manuscript) to the appropriate spectra, and Python scripts to generate each of the figures.
