Theoretical predictions for $R_{\text{c}}^{\pm }$ calculated with $\mathrm{M}\mathrm{C}\mathrm{F}\mathrm{M}$ at NLO. The kinematic selection follows the experimental requirements. For every PDF set, the central value of the prediction is given, together with the uncertainty as prescribed from the PDF set, and the uncertainties associated with the scale variations and with the value of ${\alpha }_{\text{S}}$. The total uncertainty is given in the last column. The last row in the table gives the experimental result presented in this paper
