"Table 254" of "Measurements of top-quark pair differential and double-differential cross-sections in the $\ell$+jets channel with $pp$ collisions at $\sqrt{s}=13$ TeV using the ATLAS detector"

Covariance matrix between the Relative double-differential cross-section as function of $|p_{out}^{t,had}|$ vs $N^{jets}$ in $N^{jets}$ = 5.0 and the Relative double-differential cross-section as function of $|p_{out}^{t,had}|$ vs $N^{jets}$ in $N^{jets}$ = 5.0 at particle level in the resolved topology, accounting for the statistical and systematic uncertainties.

该协方差矩阵（Covariance matrix）对应两组相对双微分截面（Relative double-differential cross-section）之间的协方差：其一为喷注数$N^{ ext{jets}}=5.0$条件下，以强子化顶夸克的出射横向动量绝对值$|p_{ ext{out}}^{t, ext{had}}|$与喷注数$N^{ ext{jets}}$为自变量的相对双微分截面；其二为分辨型拓扑（resolved topology）的粒子层次（particle level）下、喷注数$N^{ ext{jets}}=5.0$条件下，以强子化顶夸克的出射横向动量绝对值$|p_{ ext{out}}^{t, ext{had}}|$与喷注数$N^{ ext{jets}}$为自变量的相对双微分截面，且该协方差矩阵已计入统计与系统不确定性（statistical and systematic uncertainties）。
