The fit quality for the CMS double-differential Drell–Yan data for $(1/{\mathit{\sigma }}_Z)·\mathrm{d}\mathit{\sigma }/\mathrm{d}|y_Z|$ versus $|y_Z|$, in [86], for the lowest two mass bins ($20<M<30$ and $30<M<45$ GeV) (top), the mass bins ($45<M<60$ and $60<M<120$ GeV) (middle) and the mass bins ($120<M<200$ and $200<M<1500$ GeV) (bottom), at NLO and NNLO. Note that correlated uncertainties are made available in the form of a correlation matrix, so the shift of data relative to theory cannot be shown
