class ROOT::Fit::BasicFCN<ROOT::Math::IGradientFunctionMultiDim,ROOT::Fit::UnBinData>: public ROOT::Math::BasicFitMethodFunction<ROOT::Math::IGradientFunctionMultiDim>


   BasicFCN class: base class  for the objective functions used in the fits
   It has a reference to the data and th emodel function used in the fit.
   It cannot be instantiated but constructed from the derived classes
