Figure 4: Final isovector unpolarized PDFs (shaded bands) at the largest employed nucleon boost, left: Lin et al., 1.29 GeV, right: ETMC, 1.42 GeV. The right plot also shows the quasi-PDF and the matched PDF before nucleon mass corrections. For illustration purposes, selected phenomenological parametrizations are plotted (dashed/dotted lines, no uncertainties shown) [102104]. The errors are only statistical.
