"Supplemental material: Lep1Lep2Jet1_Pz covariance matrix" of "Measurement of inclusive and differential cross sections of single top quark production in association with a W boson in proton-proton collisions at $\sqrt{s}$ = 13.6 TeV"

Covariance matrix including all uncertainties of the normalised differential cross section in bins of $p_{Z}(e^{\pm}, \mu^{\pm}, j)$ in units of $1/GeV^{2}$.

协方差矩阵（covariance matrix），包含$p_{Z}(e^{pm}, mu^{pm}, j)$分箱内归一化微分截面的全部不确定度，单位为$1/GeV^{2}$。
