The fit quality of the ATLAS $W^{-},W^{+}$ data sets for $\mathrm{d}\mathit{\sigma }/\mathrm{d}|{\mathit{\eta }}_l|$ (pb) versus $|{\mathit{\eta }}_l|$, and of the $Z$ data set for $\mathrm{d}\mathit{\sigma }/\mathrm{d}|y_Z|$ versus $|y_Z|$ [10], obtained in the NLO (left) and NNLO (right) analyses. The points shown are when the shift of data relative to the theory due to correlated systematics is included. However, this shift is small compared to the uncorrelated error for the data, so the comparison before shifts is not shown
