Function documentation

AliFemtoAvgSepCorrFctn(char* title, const int& nbins, const float& Low, const float& High)

 set up numerator
  title = "Num Qinv (MeV/c)";

AliFemtoAvgSepCorrFctn(const AliFemtoAvgSepCorrFctn& aCorrFctn)

 copy constructor

~AliFemtoAvgSepCorrFctn()

 destructor

AliFemtoAvgSepCorrFctn& operator=(const AliFemtoAvgSepCorrFctn& 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();

AliFemtoString Report()

 construct report

void AddRealPair(AliFemtoPair* aPair)

 add true pair

void AddMixedPair(AliFemtoPair* aPair)

 add mixed (background) pair

void Write()

 Write out neccessary objects

TList* GetOutputList()

 Prepare the list of objects to be written to the output

void SetPairType(AliFemtoAvgSepCorrFctn::AliFemtoPairType pairtype)

TH1D* Numerator()

{return fNumerator;}

TH1D* Denominator()

{return fDenominator;}

TH1D* Ratio()

{return fRatio;}
