"Systematic correlation matrix for $W^{\pm}$ (combined)" of "Measurement of the $W \to μν_μ$ cross-sections as a function of the muon transverse momentum in $pp$ collisions at 5.02 TeV"

The correlation matrix corresponding to all of the systematic uncertainties on the differential cross-section ($d\sigma/dp_T$) fit results for $W^+$ and $W^-$ combined together, with rows and columns ordered as $W^+$ and then $W^-$.
