Probability density function of photon emission from EM-shower as a function of cosine of the emission angle.
\f[P(\cos(\theta)) = c \times e^{b \times |\cos(\theta) - 1/n|^a}\f]
where
is a normalisation constant such that the integral of
over the full solid angle is one.
The parametrisation is taken from reference: R. Mirani, "Parametrisation of EM-showers in the ANTARES detector volume.", Doctoral thesis in computational physics, University of Amsterdam.
