This data repository contains the original figures, numerical (raw) data, scripts that where used to calculate this data, and plot scripts to reproduce the figures from the publication "General Shiba mapping for on-site four-point correlation functions" at Physical Review Research. The preprint is available on arXiv where also the LaTeX source files can be found.

Figures Fig.1 and Fig.4b have been created with the Inkscape software. Fig.2, Fig.4 and Fig.6 have been edited with the Freeform software.

For the Python scripts, the following non-standard libraries have been used: numpy 1.26.4 and matplotlib 3.8.4.

The structure of the repository is the following:
In the folder "Data" the data that was used for creating the figures of the paper are stored.
In the folder "Scripts" the scripts for creating and plotting the data are stored.
In the folder "Figures" the original figures used in the publication are stored.
