Detailed Description

template<class JArgument_t>
class JPHYSICS::JPD0Transformer_t< JArgument_t >

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

PDFs are evaluated by interpolation for:

1. distance between point source and PMT [m]
2. arrival time [ns]

The evaluation of the weights is based on:

1. effective attenuation length
