Tracking efficiency of the HLT and offline trackers as function of the transverse momentum calculated as the ratio of reconstructed tracks and simulated tracks in HIJING generated Pb--Pb events at $\sqrt{s_{\rm{NN}}}$ = $5.02$\,TeV, shown for tracks that are a) primary, b) secondary, c) findable primary, and d) findable secondary Findable tracks are defined as reconstructed tracks that have at least $70$ clusters in the TPC
