Detailed Description

Base class for the probability density function of photon emission from EM-shower as a function of the index of refraction and the cosine of the emission angle.

The implementation of this function is based on a linear interpolation of tabulated values. In this, a linear approximation of the dependence of the normalisation constant on the index of refraction is assumed. This assumption is valid to within 10^-3.
