"Statistical correlation matrix for $W^-$" 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 the statistical uncertainties on the differential cross-section ($d\sigma/dp_T$) fit results for $W^-$. To combine with $W^+$ results (Fig8a), use the rows and columns ordered as $W^+$ and then $W^-$. Assume no correlation in the statistical uncertainties between $W^+$ and $W^-$ (zero entries in the off-diagonal blocks).
