Class Description

_______________________________________________________________________

 Quadratic interpolation of TGraph
_______________________________________________________________________
TSpline2( TString title, TGraph* theGraph )
 constructor from TGraph
 TSpline is a TNamed object
~TSpline2( void )
 destructor
Double_t Eval( const Double_t x )
 returns quadratically interpolated TGraph entry around x
void BuildCoeff( void )
 no coefficients to precompute
Double_t Quadrax(const Float_t dm,const Float_t dm1,const Float_t dm2,const Float_t dm3, const Float_t cos1, const Float_t cos2, const Float_t cos3 )
 quadratic interpolation
 Revised and checked by Francois Nov, 16th, 2000
 Note the beautiful non-spontaneous symmetry breaking ...
 It was checked that the old routine gave exactly the same answers.
TSpline2( TString title, TGraph* theGraph )


void GetKnot( Int_t i, Double_t& x, Double_t& y )
