Figure Caption
Efficiencies for the Pb–Pb analysis as a function of transverse momentum. The vertical dashed line indicates the switch of the eID between the TPC and TOF and TOF-only method.
efficiency (ε_rec) of the track reconstruction; efficiency of the TPC electron identification selection (ε_TPCeID)
