"Table 319" 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 $|{y}^{t,1}|\otimes |{y}^{t,2}|$ absolute differential cross-section at particle level for 0 < $|{y}^{t,1}|$ < 0.2 and the $|{y}^{t,1}|\otimes |{y}^{t,2}|$ absolute differential cross-section at particle level for 1 < $|{y}^{t,1}|$ < 2.

粒子层面上，满足$0 < |y^{t,1}| < 0.2$的$|y^{t,1}| otimes |y^{t,2}|$绝对微分截面（absolute differential cross-section），与满足$1 < |y^{t,1}| < 2$的$|y^{t,1}| otimes |y^{t,2}|$绝对微分截面之间的协方差矩阵。
