Covariance matrix between the Absolute double-differential cross-section as function of $m^{t\bar{t}}$ vs $|y^{t\bar{t}}|$ in 1.2 < $|y^{t\bar{t}}|$ < 2.5 and the Absolute double-differential cross-section as function of $m^{t\bar{t}}$ vs $|y^{t\bar{t}}|$ in 0.8 < $|y^{t\bar{t}}|$ < 1.2 at particle level in the resolved topology, accounting for the statistical and systematic uncertainties.

本数据集为粒子层面分辨型拓扑（resolved topology）下，两组以顶夸克-反顶夸克对不变质量$m^{tar{t}}$与顶夸克-反顶夸克对快度绝对值$|y^{tar{t}}|$为双变量的绝对双微分截面（Absolute double-differential cross-section）之间的协方差矩阵（covariance matrix）：其中一组的快度范围满足$1.2 < |y^{tar{t}}| < 2.5$，另一组的快度范围满足$0.8 < |y^{tar{t}}| < 1.2$。该协方差矩阵已计入统计不确定性与系统不确定性。
