class AliForwardFlowTaskQC: public AliAnalysisTaskSE

  Default constructor

  Constructor

  Parameters:
   name: Name of task

  Copy constructor

  Parameters:
   o: Object to copy from

  Assignment operator

  Set flow flags, making sure the detector setup is right

  Parameters:
   flags: Flow flags

  Create output objects

  Init vertexbin objects for forward and central detectors, and add them to the lists

  Init histograms and add vertex bin histograms to the sum list

  Calls the analyze function - called every event

  Parameters:
   option: Not used

  Load forward and central detector objects from aod tree and call the
  cumulants calculation for the correct vertex bin

  Return: true on success

  Loops over list of VtxBins, fills hists of bins for current vertex
  and runs analysis on those bins

  Parameters:
   list:  list of VtxBins
   h:     dN/detadphi histogram
   vtx:   current vertex bin
   flags: extra flags to handle calculations.

   Note: The while loop is used in this function and the next 2 for historical reasons,
         as originally each moment had it's own VertexBin object.

  Loops over list of VtxBins, fills hists of bins for current vertex
  and runs analysis on those bins

  Parameters:
   list:  list of VtxBins
   href:  dN/detadphi histogram for ref. flow
   hdiff: dN/detadphi histogram for diff. flow
   vBin:  current vertex bin
   flags: extra flags to handle calculations.

  Loops over list of VtxBins, fills hists of bins for current vertex
  and runs analysis on those bins

  Parameters:
   list:  list of VtxBins
   hcent: dN/detadphi histogram for central coverage
   hfwd:  dN/detadphi histogram for forward coverage
   vBin:  current vertex bin
   flags: extra flags to handle calculations.

  Combines a forward and central d^2N/detadphi histogram.
  At some point it might need a flag to choose which histogram gets
  priority when there is an overlap, at the moment the average is chosen

  Parameters:
    hcent: Central barrel detector
    hfwd: Forward detector

  Return: reference to combined hist

  Get TPC tracks to use for reference flow.

  Return: TObjArray with tracks

  Calls the finalize function, done at the end of the analysis

  Parameters:
   option: Not used

  Finalize command, called by Terminate()

  Loop over VertexBin list and call terminate on each

  Parameters:
   list: VertexBin list

 Loop over a list containing a TH2D with flow results
 and project to TH1's in specific centrality bins

 Parameters:
  list: Flow results list

  Function to check that an AOD event meets the cuts

  Parameters:
   AliAODForwardMult: forward mult object with trigger and vertex info

  Return: false if there is no trigger or if the centrality or vertex
  is out of range. Otherwise true.

  Function to look for a trigger string in the event.
  First check for info in forward mult object, if not there, use the AOD header

  Parameters:
   AliAODForwardMult: forward mult object with trigger and vertex info

  Return: true if offline trigger is present

  Function to look get centrality of the event.
  First check for info in forward mult object, if not there, use the AOD header

  Parameters:
   AliAODForwardMult: forward mult object with trigger and vertex info

  Return: true if centrality determination is present

  Function to look for vertex determination in the event.
  First check for info in forward mult object, if not there, use the AOD header

  Parameters:
   AliAODForwardMult: forward mult object with trigger and vertex info

  Return: true if vertex is determined

  Get VZERO object from ESD or AOD

  Return: VZERO data object

  Loops over VZERO data object and fill up d^2N/detadphi histogram for flow analysis

  Parameters:
   vzero: VZERO AOD data object

  Print the setup of the flow task

  Get the type of the QC calculations
  Used for naming of objects in the VertexBin class,
  important to avoid memory problems when running multiple
  initializations of the class with different setups

  Parameters:
   flags: Flow flags for type determination
   prependUS: Prepend an underscore (_) to the name

  Return: QC calculation type
