Detailed Description

template<class JArgument_t>
class JPHYSICS::JPDFTransformer< 4, JArgument_t >

Template specialisation of transformer of the 4D probability density function (PDF) of the time response of a PMT due to an EM shower.

PDFs are evaluated by interpolation for:

1. distance between EM shower and PMT [m]
2. cosine angle EM shower direction and EM shower - PMT position
3. zenith angle of the PMT
4. azimuthal angle of the PMT
5. 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
