class AlidNdPtTrackDumpTask: public AliAnalysisTaskSE

 Constructor

 Create histograms
 Called once

 Called for each event

 Select real events with high-pT tracks

 Select real events with high-pT tracks

 Process laser events

 Select real events with high-pT tracks
 Calculate and stor in the output tree:
  TPC constrained tracks
  InnerParams constrained tracks
  TPC-ITS tracks
  ITSout-InnerParams tracks
  chi2 distance between TPC constrained and TPC-ITS tracks
  chi2 distance between TPC refitted constrained and TPC-ITS tracks
  chi2 distance between ITSout and InnerParams tracks
  MC information:
   track references at ITSin, TPCin; InnerParam at first TPC track reference,
   particle ID, mother ID, production mechanism ...

 Fill tree for efficiency studies MC only

 check if particle is Z > 1

 Select real events with V0 (K0s and Lambda) high-pT candidates

 Select real events with large TPC dEdx signal

 Create KF particle in case the V0 fullfill selection criteria

 Selection criteria
  0. algorithm cut
  1. track cut
  3. chi2 cut
  4. rough mass cut
  5. Normalized pointing angle cut

 Downscale randomly low pt V0

return kFALSE;

 Constrain TPC inner params constrained

 Constrain TPC inner params constrained
