Covariance matrix between the Relative double-differential cross-section as function of $p_{T}^{t,had}$ vs $m^{t\bar{t}}$ in 200.0 GeV < $m^{t\bar{t}}$ < 400.0 GeV and the Relative double-differential cross-section as function of $p_{T}^{t,had}$ vs $m^{t\bar{t}}$ in 200.0 GeV < $m^{t\bar{t}}$ < 400.0 GeV at particle level in the resolved topology, accounting for the statistical and systematic uncertainties.

本协方差矩阵为200.0 GeV < $m^{tar{t}}$ < 400.0 GeV范围内，以$p_{T}^{t,{
m had}}$和$m^{tar{t}}$为变量的相对双微分截面（Relative double-differential cross-section），与粒子层面分辨型拓扑下、相同不变质量区间内的上述相对双微分截面之间的协方差矩阵，且该矩阵计入了统计不确定性与系统不确定性。
