3873f6ee 17// (AliAnalysisTaskCheckCascade)
32599cd4 18// This task has four roles :
3873f6ee 19// 1. QAing the Cascades from ESD and AOD
20// Origin: AliAnalysisTaskESDCheckV0 by B.H. Nov2007, hippolyt@in2p3.fr
32599cd4 21// 2. Prepare the plots which stand as raw material for yield extraction (wi/wo PID)
22// 3. Supply an AliCFContainer meant to define the optimised topological selections
23// 4. Rough azimuthal correlation study (Eta, Phi)
3873f6ee 24// Adapted to Cascade : A.Maire Mar2008, antonin.maire@ires.in2p3.fr
c525f360 25// Modified : A.Maire Nov2010, antonin.maire@ires.in2p3.fr
