class AliFemtoModelCorrFctnNonIdDR: public AliFemtoModelCorrFctn


AliFemtoModelCorrFctnNonIdDR - correlation function for non-identical
particles which uses k* as a function variable. Stores the correlation
function separately for positive and negative signs of k* projections into
out, side and long directions, enabling the calculations of double ratios
Uses pair weight to simulate the model correlation function.

Function documentation

AliFemtoModelCorrFctnNonIdDR(char* title, const int& nbins, const float& QinvLo, const float& QinvHi)

 Default constructor

AliFemtoModelCorrFctnNonIdDR(const AliFemtoModelCorrFctnNonIdDR& aCorrFctn)

 copy constructor

~AliFemtoModelCorrFctnNonIdDR()

 Destructor

AliFemtoModelCorrFctnNonIdDR& operator=(const AliFemtoModelCorrFctnNonIdDR& aCorrFctn)

 assignment operator

void Finish()

 here is where we should normalize, fit, etc...
 we should NOT Draw() the histos (as I had done it below),
 since we want to insulate ourselves from root at this level
 of the code.  Do it instead at root command line with browser.
  fNumerator->Draw();
fDenominator->Draw();
fRatio->Draw();
  fRatio->Divide(fNumerator,fDenominator,1.0,1.0);

AliFemtoString Report()

 construct report

void AddRealPair(AliFemtoPair* aPair)

 add true pair

void AddMixedPair(AliFemtoPair* aPair)

 add mixed (background) pair

void Write()

 Write out histos

TList* GetOutputList()

 Prepare the list of objects to be written to the output
