This folder contains the parameters which are inserted into the susceptiblity model. The values are saved in 3 csvs, "amplitudes","widths (HWHM)", "energies"

The values are extrapolated from fitting to the exciton spectrum. Where possible the fitted values are used.

The parameters are saved in csv files in 2D arrays. Note, the matrix elements for transitions between Rydberg states are in their own folder.

Also saved here is "fitted_parameter_trends_March_2023.csv" which contaons the values used for the extrapolation of values to higher n. The details of how these extrapolations were performed is in the Appendices of the paper.

"AM04_fitpara.csv" coantains fits to SHG spectra (to extract the widths and energies of S and D states). Details of this experiment and fitting are available in doi:10.1103/PhysRevB.105.115206
