Detailed Description

template<class JArgument_t>
class JPHYSICS::JPDFTransformer_t< JArgument_t >

Transformer for the 1D probability density function (PDF) of the time response of a PMT to a muon.

PDFs are evaluated by interpolation for:

distance of closest approach of the muon to the PMT [m]
arrival time [ns]

The evaluation of the weights is based on:

effective attenuation length
