class AliCaloCalibPedestal: public TObject


 A help class for monitoring and calibration tools: MOOD, AMORE etc.,
 It can be created and used a la (ctor):

  //Create the object for making the histograms
  fPedestals = new AliCaloCalibPedestal( fDetType );
  // AliCaloCalibPedestal knows how many modules we have for PHOS or EMCAL
  fNumModules = fPedestals->GetModules();

 fed an event:
  fPedestals->ProcessEvent(fCaloRawStream);
 asked to draw histograms:
  fPedestals->GetDeadMap(i)->Draw("col");
 or
  fPedestals->GetPeakProfileHighGainRatio((i < fNumModules) ? i : fVisibleModule)->Draw("colz");
 etc.
 The pseudo-code examples above were from the first implementation in MOOD (summer 2007).

AliCaloCalibPedestal

Function documentation

AliCaloCalibPedestal(kDetType detectorType)

Default constructor. First we set the detector-type related constants.

void ValidateProfiles()

Make sure the basic histos exist

void CompressAndSetOwner()

Compress the arrays, in order to remove the empty objects (a 16 slot array is created by default)

~AliCaloCalibPedestal()

dtor

AliCaloCalibPedestal(AliCaloCalibPedestal& ped)

 Then the ObjArray ones; we add the histograms rather than trying TObjArray = assignment
DS: this has not really been tested yet..

void Reset()

void SetParametersFromFile(const char* parameterFile)

 Note: this method is a bit more complicated than it really has to be
 - allowing for multiple entries per line, arbitrary order of the
 different variables etc. But I wanted to try and do this in as
 correct a C++ way as I could (as an exercise).

void WriteParametersToFile(const char* parameterFile)

Write parameters in file.

Bool_t AddInfo(AliCaloCalibPedestal* ped)

 just do this for the basic histograms/profiles that get filled in ProcessEvent
 may not have data for all modules, but let's just Add everything..

Bool_t ProcessEvent(AliRawReader* rawReader)

 if fMapping is NULL the rawstream will crate its own mapping

Bool_t ProcessEvent(AliCaloRawStreamV3* in)

 Method to process=analyze one event in the data stream

Bool_t SaveHistograms(TString fileName, Bool_t saveEmptyHistos = kFALSE)

Saves all the histograms (or profiles, to be accurate) to the designated file

Bool_t LoadReferenceCalib(TString fileName, TString objectName)

Bool_t SetReference(AliCaloCalibPedestal* ref)

void ValidateComparisonProfiles()

Make sure the comparison histos exist

void ComputeDiffAndRatio()

void ComputeHotAndWarningTowers(const char* hotMapFile = 0)

void ComputeDeadTowers(const char* deadMapFile = 0)

Bool_t IsBadChannel(int imod, int icol, int irow) const
