Pure abstract base class for defining a variation across a 2D DP.
virtual Double_t getHistNorm() const =0
Retrieve PDF normalisation.
virtual Double_t getMaxHeight() const =0
Retrieve maximum height.
virtual Double_t interpolateXY(Double_t x, Double_t y) const =0
Perform the interpolation (unnormalised)
virtual Double_t interpolateXYNorm(Double_t x, Double_t y) const =0
Perform the interpolation and divide by the normalisation.
Lau2DAbsDPPdf()
Constructor.
Lau2DAbsDPPdf & operator=(const Lau2DAbsDPPdf &rhs)
