 $\RPO$\ versus \pT\ for charged particles at midrapidity in \PbPb\ collisions at $\snn=5.02$ TeV. $\RPO$\ is defined as the ratio of $\Ncoll$ normalized spectra for a given centrality class relative to the 5\% more central class, see \Eq{eq:rpo} The filled, coloured markers are for the 5 most peripheral classes, with the corresponding global uncertainties denoted close to $\pt = 0.1$~\gevc\ on the \pt-axis Vertical error bars denote statistical uncertainties, while the boxes denote the systematic uncertainties. For visibility, the uncertainties are only drawn for the peripheral classes.
