Auxiliary material accompanying "Precision renormalisation and improvement of $N_{\rm f}=3$ lattice QCD with Wilson fermions"

This dataset contains the fit parameters, covariance matrices, and example Python code required to reconstruct the interpolations presented in the accompanying publication "Precision renormalisation and improvement of Nf=3 lattice QCD with Wilson fermions". The dataset provides parameterizations of the quark mass combinations m14 and m45, as well as the renormalization factors ZA and ZP, for the lattice volumes and bare couplings considered in the study. Full covariance matrices are included to enable the propagation of statistical uncertainties and correlations. The files consist of a JSON data file containing the fit parameters and covariance matrices, together with Python scripts demonstrating how to reconstruct the interpolations and their uncertainties. A minimal working example is provided.
