Fig. 14.

Same as Fig. 8, but now comparing a combined MC PDF set with $N_{\mathrm{rep}}=300$ replicas to its MC-H Hessian representation with $N_{\mathrm{eig}}=90$ eigenvector. The starting set is obtained from the combination of Monte Carlo representations of the NNPDF3.0, CT14 and MMHT14 NNLO PDF sets containing $N_{\mathrm{rep}}=100$ replicas each
