Table 4.

The quality of the description (as measured by the value of ${\mathit{\chi }}^2$) of the LHC inclusive jet data before and after they are included in the global NLO and NNLO fits. We also show for comparison the ${\mathit{\chi }}^2$ values obtained in the CPdeut fit of the NLO MMSTWW analysis [11], which did not include LHC data. Also the LHC jet data are not included in the final NNLO MMHT global fit presented in this paper. However, the NNLO ${\mathit{\chi }}^2$ numbers and $K$ factors mentioned in the table correspond to an exploratory approximate NNLO study described in Sect. 4.3.1
