"Table 1026" 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 Absolute double-differential cross-section as function of $m^{t\bar{t}}$ vs $N^{extra jets}$ in $N^{extra jets}$ $\geq$ 2.0 and the Absolute double-differential cross-section as function of $m^{t\bar{t}}$ vs $N^{extra jets}$ in $N^{extra jets}$ = 0.0 at particle level in the boosted topology, accounting for the statistical and systematic uncertainties.

本数据集为增压拓扑（boosted topology）下粒子层次（particle level）中，两类绝对双微分截面（Absolute double-differential cross-section）间的协方差矩阵：其一为以顶夸克-反顶夸克对不变质量（$m^{tar{t}}$）与额外喷动数目（$N^{extra jets}$）为变量且满足$N^{extra jets} geq 2.0$的绝对双微分截面；其二为以相同变量为函数且$N^{extra jets} = 0.0$的绝对双微分截面。该协方差矩阵已计入统计与系统不确定度。
