Normalized $\Sigma_{\text{EEC}}$ as a function of $\langle\pTchjet\rangle\RL$. $\ln\langle\pTchjet\rangle$ in the y-axis represents $\ln(\langle\pTchjet\rangle/(\GeVc))$, a unit-less number, used throughout this paper for simplicity in notation. The gray line corresponds to the maximum location of the distribution and the gray band corresponds to a $\pm$0.14 \GeVc~uncertainty along the x-axis. The orange curves show pQCD calculations ~, which are normalized to data such that the integral inside \RL~range of 12~\GeVc/$\langle\pTchjet\rangle$, marked by the vertical dashed orange line, to 0.4 are the same. The purple curve represents a linear functional form that is fit to data ($\chi^2 = 1.65$) in the \RL~range of 0.01 to $0.7~\GeVc/\langle\pTchjet\rangle$, marked by the vertical dashed purple line. As the fitting range for the linear curve is mostly accessible by the data in 20--40 \GeVc, the comparison of linear fit to data is only shown for 20--40 \GeVc. As the normalization range for the orange pQCD curve is mostly accessible by the data in 60--80 \GeVc, the comparison of pQCD to data is only shown for 60--80 \GeVc.
