"Figure 2 (1960 GeV CH3 covariance)" of "Energy-scaling behavior of intrinsic transverse momentum parameters in Drell-Yan simulation"

Covariance of the data uncertainty contribution to the tuned intrinsic kT parameters between the two generator settings of Herwig at proton-anti-proton center-of-mass energy 1960 GeV.

在质子-反质子质心能量1960 GeV条件下，Herwig的两种生成器设置之间，数据不确定性（data uncertainty）对调谐的本征kT参数贡献的协方差（Covariance）。
