"Figure 8, FWD" of "Measurement of $\psi(2S)$ nuclear modification at backward and forward rapidity in $p$ $+$ $p$, $p$ $+$ Al, and $p$ $+$ Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV"

Invariant yield ratio of PSI(2S)-->MU+MU- with respect to J/PSI(1S)-->MU+MU- in p+Au collisions as a function of centrality at forward rapidity. The statistical and systematic uncertainties vary point-to-point and are listed for each measured value. The global systematic uncertainty cancels when taking the ratio.
