class AliAnalysisTaskCheckCascadepp276: public AliAnalysisTaskSE
AliAnalysisTaskCheckCascadepp276 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)
Adapted to Cascade : A.Maire Mar2008, antonin.maire@ires.in2p3.fr
Modified : A.Maire Mar2010
Adapted to PbPb analysis: M. Nicassio, maria.nicassio@ba.infn.it
Feb-August2011
- Physics selection moved to the run.C macro
- Centrality selection added (+ setters) and histos
- flag and setters added (CF container usage, vertex range)
- histo added and histo/container binning changed
- protection in the destructor for CAF usage
- AliWarning disabled
- number of tracklets from AOD also
- automatic settings for PID
September2011
- proper time histos/container added (V0 and Cascades)
- cosine PA V0 wrt Xi vertex in the container
November2011
- re-run V0's and cascade's vertexers (SetCuts instead SetDefaultCuts!!)
- problems of libraries on Grid --> code copied in the task (from AliRoot v5-10-AN
where new pt dependent V0's cosPA cut implemented by Iouri)
- AOD analysis part completed
Adapted to pp 2.76 TeV analysis: D. Colella, domenico.colella@ba.infn.it
Gen-now 2012
- Physics selection re-moved here (mainly for normalization in the efficiency calcuation)
- Centrality selection deleted
Adapted to pPb 5.02 TeV analysis: D. Colella, domenico.colella@ba.infn.it
Aug-Sep 2014
- Added the parameter fCollidingSystem, to distingish between pp and pPb procedures
