Comparison of the rapidity dependence of $R_{\rm{pPb}}$ for \psip in p--Pb collisions at $\sqrtSnn = 8.16$ and 5.02 TeV . The error bars represent the statistical uncertainties, while the boxes correspond to uncorrelated systematic uncertainties and the boxes at $R_{\rm pPb}=1$ to correlated systematic uncertainties, separately shown for the two energies. The results are also compared with theoretical models that include final-state effects .
