  18 // Modified version of AliAnalysisTaskCheckCascade.cxx.
  19 // This is a 'hybrid' output version, in that it uses a classic TTree
  20 // ROOT object to store the candidates, plus a couple of histograms filled on
  21 // a per-event basis for storing variables too numerous to put in a tree.
  22 //
  23 // --- Adapted to look for lambdas as well, using code from
  24 //        AliAnalysisTaskCheckPerformanceStrange.cxx
  25 //
  26 //  --- Algorithm Description
  27 //   1. Loop over primaries in stack to acquire generated charged Xi
  28 //   2. Loop over stack to find Cascades, fill TH3Fs "PrimRawPt"s for Efficiency
  29 //   3. Perform Physics Selection
  30 //   4. Perform Primary Vertex |z|<10cm selection
  31 //   5. Perform Primary Vertex NoTPCOnly vertexing selection (>0 contrib.)
  32 //   6. Perform Pileup Rejection
  33 //   7. Analysis Loops:
  34 //    7a. Fill TH3Fs "PrimAnalysisPt" for control purposes only
  35 //
  36 //  Please Report Any Bugs!
