To illustrate the accuracy that the EIC can reach in the determination of nuclear gluon PDF we show in Fig. [ref] their relative uncertainties alongside those of the proton's NNPDF2.0 [ref] combined with those of the EPS09 nuclear modifications [ref] for $^208Pb$, The NNPDF2.0 and EPS09 relative uncertainties have been added linearly for a conservative estimate of the total uncertainty.
