Detailed Description

template<class JArgument_t>
class JPHYSICS::JPDFTransformer< 3, JArgument_t >

Template specialisation of transformer of the 3D Probability Density Functions of the time response of a PMT.

PDFs are evaluated by interpolation for:

1. distance of closest approach of the muon to the PMT [m]
2. zenith angle of the PMT
3. azimuthal angle of the PMT
4. arrival time [ns]

The evaluation of the weights is based on:

1. effective attenuation length
2. emission profile of the photons
3. angular acceptance of PMT
