 > ## Solution 2.5
 > The x-axis is plotted as a function of $\mu$ as this is a true measurement of pileup (additional interactions) and not just some variable which is correlated with pileup. Other options might have been $N_{PV}$, which has an efficiency which is less than 100%, and $\rho$, which assumes that the pileup energy density is uniform. We also get different values of $\rho$ if we measure it for different regions in $\eta$ (i.e. $|\eta|<3$ or $|\eta|<5$).
