Comparison of the charge-weighted EEC in pp collisions with five different Monte Carlo models in each interval of $p_{\mathrm{T,ch\,jet}}$. In the first row, statistical uncertainties on the data are shown as vertical lines, and systematic uncertainties are shown as shaded boxes. Statistical uncertainties on the five models are shown as shaded bands around the lines but are mostly too small to be seen. For the model-to-data ratios displayed in the bottom two rows, the relative combined statistical and systematic uncertainties on the data are shown as shaded gray boxes surrounding the dashed unity line. The relative statistical uncertainties from the models are shown as colored shaded bands around each line.
