"Table 245" of "Measurements of top-quark pair single- and double-differential cross-sections in the all-hadronic channel in $pp$ collisions at $\sqrt{s}=13~\textrm{TeV}$ using the ATLAS detector"

Covariance matrix between the absolute double-differential cross-section as function of $|P_{out}^{t,1}|$ vs $N_{jets}$ in $N_{jets}$ = 8 and the absolute double-differential cross-section as function of $|P_{out}^{t,1}|$ vs $N_{jets}$ in $N_{jets}$ = 8 at particle level in the all hadronic resolved topology, accounting for the statistical and systematic uncertainties.

本协方差矩阵对应全强子分辨拓扑结构（all hadronic resolved topology）的粒子级（particle level）场景，其涉及的两组绝对双微分截面（absolute double-differential cross-section）均满足喷注数目$N_{jets}=8$的条件，且均以$|P_{out}^{t,1}|$与喷注数目$N_{jets}$为自变量，该矩阵同时计入了统计不确定度与系统不确定度。
