  // - Whether to use TH2::ProjectionX 
  task->SetUseROOTProjectX(false);

  // --- Special for Hans' analysis ----------------------------------
  // - Set the filename of the corresponding MC analysis
  // const char* mcanalysisfilename = 
  //    "/home/hehi/alex/work/dispVtxDNdeta/mcCorrectionPos.root"
  // task->SetMCFinalCorrFilename(mcanalysisfilename);

  // --- Other things we may overwrite -------------------------------
  // - Set the vertex range to use 
  // task->SetIpZRange(vzMin, vzMax);

  // - Set the trigger mask to use (INEL,INEL>0,NSD)
  // task->SetTriggerMask(trig);

  // - Set the trigger efficiency 
  // task->SetTriggerEff(trigEff); // 0.997535);

  // - Set how to normalize. Bit mask of
  // 
  //    kNone           Normalise to accepted events 
  //    kEventLevel     Normalise to all events in selected range 
  //    kAltEventLevel  Normalise to all events in selected range 
  //    kBackground     Also correct for background triggers 
  // 
  //   kNone, kEventLevel, and kAltEventLevel are mutually exclusive.
  //   If neither kEventLevel, nor kAltEventLevel is specified, then
  //   kNone is assumed.  kBackground (when implemented) only makes
  //   sense with kEventLevel and kAltEventLevel.  Furthermore, there

  //    kPileupNormal	Use the flag from AOD (default)
  //    kPileupSPD	Check the pile-up flag from SPD 
  //    kPileupTrk	Check the pileup flag from tracks 
  //    kPileupBC	Check the out-of-bunch pileup flag

  //   vertices rather than tracklet vertices
  // au.SetUseMVPlpSelection(false);

  //   - nTrkL < 20 MinPlpContribSPD=3, 
  //   - nTrkL < 50 MinPlpContribSPD=4

  //   nSigmaDiamZSPD=5.
  // au.SetUseSPDCutInMultBins(false);
  // - Least number of contributors to tracklet pile-up vertex

  // - Least distance along Z between primary and tracklet pile-up
  //   vertex (cm)
  // au.SetMinPlpZdistSPD(0.8);
  // - Least distance along Z between primary and tracklet pile-up
  //   vertex in terms of the errors on the vertices
  // au.SetnSigmaPlpZdistSPD(3);

  //   sigma along Z of the interaction diamond.
  // au.SetnSigmaPlpDiamZ(5);

  // - Set whether to check for SPD outliers 
  // task->SetCheckSPDOutlier(false);

  // - Set the centrality estimator to use 
  // task->SetCentralityMethod(cent);

  // - Set the centrality bins to use.  These are mutually exclusive.
  //   Note, that a bin specified as a-b, covers the interval from a,
  //   inclusive to b exclusive.  An upper bound of 100 is treated
  //   especially, and the upper bound is inclusive in that case .
