"Table 498" 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 $|{y}^{t,1}|\otimes |{y}^{t,2}|$ normalized differential cross-section at particle level for 0 < $|{y}^{t,1}|$ < 0.2 and the $|{y}^{t,1}|\otimes |{y}^{t,2}|$ normalized differential cross-section at particle level for 0.5 < $|{y}^{t,1}|$ < 1.
