7 | // AliAnalysisTaskCheckCascadePbPb class | |
8 | // Origin AliAnalysisTaskCheckCascade | |
9 | // This task has four roles : | |
10 | // 1. QAing the Cascades from ESD and AOD | |
11 | // Origin: AliAnalysisTaskESDCheckV0 by Boris Hippolyte Nov2007, hippolyt@in2p3.fr | |
12 | // 2. Prepare the plots which stand as raw material for yield extraction (wi/wo PID) | |
13 | // 3. Supply an AliCFContainer meant to define the optimised topological selections | |
14 | // 4. Rough azimuthal correlation study (Eta, Phi) | |
15 | // Adapted to Cascade : A.Maire Mar2008, antonin.maire@ires.in2p3.fr | |
16 | // Modified : A.Maire Mar2010, antonin.maire@ires.in2p3.fr | |
