"Table 229" of "Measurement of differential cross sections for the production of top quark pairs and of additional jets in lepton+jets events from pp collisions at $\sqrt{s} =$ 13 TeV"

Covariance matrix of normalized cross section at the parton level as a function of $|y(\text{t}_\text{h})|$ vs. $p_\text{T}(\text{t}_\text{h})$.

以顶强子t_h的快度绝对值|y(t_h)|与横向动量p_T(t_h)为变量的部分子层次（parton level）下归一化截面（normalized cross section）的协方差矩阵（Covariance matrix）。
