"pp MC stats covariance matrix for girth for $x_J$>0.8" of "Girth and groomed radius of jets recoiling against isolated photons in lead-lead and proton-proton collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV"

Covariance matrix of the statistical uncertainty in MC for the unfolded jet girth distribution in pp for jets that pass the $x_J$>0.8 selection.The bin indices correspond to the bins used in the jet girth distribution.

满足x_J>0.8选择条件的喷流在质子-质子（pp）对撞中的展开喷流宽度分布（unfolded jet girth distribution）对应的蒙特卡洛（MC）统计不确定性（statistical uncertainty）的协方差矩阵（covariance matrix）。Bin索引（bin indices）对应于喷流宽度分布中使用的bin。
