SUMMARY :
Preparation of the p+p 7 TeV analyses.
---------------------------
1. CheckCascade :
* Trigger Selection :
introduction of TString fTriggerMaskType = type of trigger to use in UserExec : AliVEvent::kMB or kHighMult ?
Note : default = event is selected in the task
* Pile-up :
introduction of Bool_t fkRejectEventPileUp = kTRUE to enable the rejection of events tagged as pile-up by SPD (AliESDEvent::IsPileupFromSPD)
+ control plot : TH1F fHistCascadeMultiplicityForTrigEvtNonPiledUpAndZprimVtx
* Primary tracks & Multiplicity bins :
nTrackPrimaryMultiplicity = fESDtrackCuts->CountAcceptedTracks(lESDevent)
TH1F fHistPrimaryTrackMultiplicityForTrigEvt,
TH1F fHistPrimaryTrackMultiplicityForCascadeEvt
* Armenteros plot :
Fix following Lee Barnby's suggestion : f2dHistArmenteros->Fill( lChargeXi*lAlphaXi, lPtArmXi );
* c.Tau :
TH1F fHistcTauXiMinus to check (x4), filled with cascade candidates : Mpdg +- 10 MeV/c2 ~ Mpdg +- 5sigma
* TPC PID :
introduction of a new set of param. for the TPC PID (Aleph param.) for LHC10d p+p Pass2.
= feature of the "one pad cluster" reconstruction in TPC.
Bool_t fkIsDataRecoWith1PadTPCCluster = switch from one case to the other
Almost official, got from A.Kalweit
fAlephParameters[0] = 1.28949/50.;
fAlephParameters[1] = 2.74095e+01;
fAlephParameters[2] = TMath::Exp(-3.21763e+01);
fAlephParameters[3] = 2.44026;
fAlephParameters[4] = 6.58800;
Logically, the same problem holds for the recent MC prod (LHC10fa6) : a new parameterization will also be needed for MC ...
Home made param. (temporary)
fAlephParameters[0] = 0.04;
fAlephParameters[1] = 17.5;
fAlephParameters[2] = 3.4e-09;
fAlephParameters[3] = 2.15;
fAlephParameters[4] = 3.91720e+00;
* Angular correlation :
- retain only primary tracks (use of AliESDtrackCuts)
- option to exclude cascade whose pt < ... GeV/c
- introduction of 3 options to follow for the correlations:
1.1 - "TrigAnyCasc-AssoAnyPrim"
1.2 - "TrigCascLeading-AssoAnyPrim"
2. - "TrigLeadingTrck-AssoCasc" (= default)
TString fAngularCorrelationType = data member used for the option switch
3. CheckPerformance
* Trigger Selection :
introduction of TString fTriggerMaskType = type of trigger to use in UserExec : AliVEvent::kMB or kHighMult ?
Note : default = event is selected in the task
* Pile-up :
introduction of Bool_t fkRejectEventPileUp = kTRUE to enable the rejection of events tagged as pile-up by SPD (AliESDEvent::IsPileupFromSPD)
+ control plot : TH1F fHistCascadeMultiplicityForTrigEvtNonPiledUpAndZprimVtx
* Primary tracks & Multiplicity bins :
nTrackPrimaryMultiplicity = fESDtrackCuts->CountAcceptedTracks(lESDevent)
TH1F fHistMCTrackMultiplicity is now filled with AliStack::GetNprimary()
* Resolution of the phi angle :
TH2F DeltaPhi(MC casc,Reco casc) vs Pt(mc) (azimuthal correlation ...) x4
* Resolution of multiplicity estimator :
TH2F f2dHistRecoMultVsMCMult : Reco prim tracks Vs MC gen. primaries (eta<0.8)
* TPC PID :
introduction of a new set of param. for the TPC PID (Aleph param.) for LHC10f6a prod = MC for LHC10d Pass2.

new functions, mc analysis can be performed also for pi0 and k0. eta of seed can be restricted to inner acceptance range in order to get whole cone in normal acceptance

Small update to distinguish, in the HV plot, channels which are OFF, from channels which tripped during the run (those are set to a value of -1) (Laurent)

To finally (!) be able to cut on HV values, a method AliMUONCalibrationData::PatchHVValues was added,
which will remove extraneous HV values (read from OCDB) in the cases where
the ramp-down was started before the end of run
At the same time, AliMUONRecoParam was updated to a) remove the high limit on HV (not likely to be
ever used) b) have one HV (low) limit per chamber, instead of just St12 vs St345, so we have a finer
control.

Add the new trigger classes for Pb-Pb. Add 2 new rubrics to count the events/tracks within 2 centrality regions (60-80% and 0-10%) and w/wo acceptance cuts. Add the possibility to select tracks in the acceptance to fill histograms, by default all tracks from all events are used (Philippe P.)
