"Table 988" 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 $p_{T}^{t,had}$ vs $N^{extra jets}$ in $N^{extra jets}$ = 2.0 and the Relative double-differential cross-section as function of $p_{T}^{t,had}$ vs $N^{extra jets}$ in $N^{extra jets}$ = 2.0 at particle level in the boosted topology, accounting for the statistical and systematic uncertainties.

本数据集为两种条件下，以强子化顶夸克横动量（$p_{T}^{t,had}$）与额外喷流数目（$N^{extra jets}$）为自变量的相对双微分截面（Relative double-differential cross-section）之间的协方差矩阵（covariance matrix）：其一为额外喷流数目固定为2.0时的对应截面；其二为在boosted拓扑（boosted topology）的粒子层面下，且额外喷流数目同样固定为2.0时的对应截面。该协方差矩阵已计入统计与系统不确定性。
