 \section trigger_s5 How to get trigger chamber efficiency from data
 
-Trigger chamber efficiency map is calculated during reconstruction and saved in AliESDs.root
+Trigger chamber efficiency map is calculated from AliESDs.root with the analysis task: PWG3/muon/AliMUONTriggerChamberEff.
+The output of the task is a file filename="MUON.TriggerEfficiencyMap.root" containing the numerator and denominator histograms for the efficiency calculation.
 In order to view and save the map, use macro MUONTriggerChamberEfficiency.C
