32599cd4 | 9 | // This task has four roles : |
3873f6ee | 10 | // 1. QAing the Cascades from ESD and AOD |
11 | // Origin: AliAnalysisTaskESDCheckV0 by B.H. Nov2007, hippolyt@in2p3.fr | |
32599cd4 | 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) | |
