Integrated fiducial cross sections times leptonic branching ratios of ${\mathit{\sigma }}_{W^{+}\to {\ell }^{+}\mathit{\nu }}^{\mathrm{fid}}$ vs. ${\mathit{\sigma }}_{W^{-}\to {\ell }^{-}\overline{\mathit{\nu }}}^{\mathrm{fid}}$ (left) and ${\mathit{\sigma }}_{W^{\pm }\to {\ell }^{\pm }\mathit{\nu }}^{\mathrm{fid}}$ vs. ${\mathit{\sigma }}_{Z/{\mathit{\gamma }}^{\ast }\to {\ell }^{+}{\ell }^{-}}^{\mathrm{fid}}$ (right). The data ellipses illustrate the 68% CL coverage for the total uncertainties (full green) and total excluding the luminosity uncertainty (open black). Theoretical predictions based on various PDF sets are shown with open symbols of different colours. The uncertainties of the theoretical calculations correspond to the PDF uncertainties only
