"Table 495" of "Differential $t\bar{t}$ cross-section measurements using boosted top quarks in the all-hadronic final state with 139 fb$^{-1}$ of ATLAS data"

Covariance matrix between the $p_{T}^{t,1}\otimes p_{T}^{t,2}$ normalized differential cross-section at particle level for 0.75 TeV < $p_{T}^{t,1}$ < 2 TeV and the $p_{T}^{t,1}\otimes p_{T}^{t,2}$ normalized differential cross-section at particle level for 0.75 TeV < $p_{T}^{t,1}$ < 2 TeV.

协方差矩阵（covariance matrix）：介于满足0.75 TeV < $p_{T}^{t,1}$ < 2 TeV能区的粒子级（particle level）$p_{T}^{t,1} otimes p_{T}^{t,2}$归一化微分截面（normalized differential cross-section），与另一组同样处于该能区的同类型截面之间。
