W+ vs. W- and W (≡ W++W-) vs. Z total cross sections at 7 TeV.

Left plots: 68% C.L. Right plots: 90% C.L.
Plots below symmetrise errors where necessary. For MSTW08, CTEQ6.6, CT10, CT10W, HERAPDF1.0 and HERAPDF1.5, the correlation cosine defining the error ellipse is calculated only from the eigenvector PDF sets for the central αS value, since a definite prescription is not clear for the calculation of the correlation cosine in the presence of αS uncertainties (and model and parameterisation uncertainties for HERAPDF1.0 and HERAPDF1.5).
