class AliAnalysisTaskCheckCascadePbPb: public AliAnalysisTaskSE
AliAnalysisTaskCheckCascadePbPb class
Origin AliAnalysisTaskCheckCascade which has four roles :
1. QAing the Cascades from ESD and AOD
Origin: AliAnalysisTaskESDCheckV0 by Boris Hippolyte Nov2007, hippolyt@in2p3.fr
2. Prepare the plots which stand as raw material for yield extraction (wi/wo PID)
3. Supply an AliCFContainer meant to define the optimised topological selections
4. Rough azimuthal correlation study (Eta, Phi)

Feb-August2011
- Physics selection moved to the run.C macro
- Centrality selection added (+ setters)
- setters added (vertex range)
- histo added and histo/container binning changed
- protection in the destructor for CAF usage
- AliWarning disabled
- automatic settings for PID
September2011
- proper time histos/container added (V0 and Cascades)
November2011
- re-run V0's and cascade's vertexers (SetCuts instead of SetDefaultCuts!!)
Genuary2012
- AOD analysis part completed
March2012
- min number of TPC clusters for track selection as a parameter
July2012
