Detailed Description

template<class JArgument_t>
class JPHYSICS::JPDFTransformer< 2, JArgument_t >

Template specialisation of transformer of the 2D Probability Density Functions of the time response of a PMT.

PDFs are evaluated by interpolation for:

distance between EM shower and PMT [m]
cosine angle EM shower direction and EM shower - PMT position
arrival time [ns]

The evaluation of the weights is based on:

effective attenuation length
emission profile of the photons
