Transverse momentum distributions of primary charged particles in $|\eta|< 0.8$ in nine centrality intervals in Pb--Pb collisions at \snn = 2.76 (left) and 5.02 TeV (right) (scale factors as indicated are used for better visibility). The data for pp collisions, obtained scaling the cross section by $\sigma^{\rm NN}_{\rm inel}$, and NSD p--Pb at $\snn = 5.02$ TeV are also shown. The relative systematic uncertainties are shown in the lower panels for various datasets; these do not contain the normalization uncertainty.
