Destructor

Main loop
Called for each event

Identify non-heavy flavour electrons using Invariant mass method KF

Create histograms

 Info("Terminate");

Prepare flow events

 Check single track cuts for a given cut step

Multiplicity TPV vs Global

 Set a centrality range ]min, max] and define the method to use for centrality selection

Set ID cuts

 set the histo for centrality flattening
 the centrality is flatten in the range minCentr,maxCentr
 if centrRef is zero, the minimum in h within (minCentr,maxCentr) defines the reference
                positive, the value of h(centrRef) defines the reference (-> the centrality distribution might be not flat in the whole desired range)
                negative, h(bin with max in range)*centrRef is used to define the reference (-> defines the maximum loss of events, also in this case the distribution might be not flat)
 switchTRand is used to set the unerflow bin of the histo: if it is < -1 in the analysis the random event selection will be done on using TRandom

  Random event selection, based on fHistCentrDistr, to flatten the centrality distribution
  Can be faster if it was required that fHistCentrDistr covers
  exactly the desired centrality range (e.g. part of the lines below should be done during the
 setting of the histo) and TH1::SetMinimum called
