Detailed Description

Auxiliary class for source tracking.

This class constitutes a function object corresponding to the normalised probability

\[ \frac{dP}{d\Omega}(cos\theta) \]

for a source to be at an observed zenith angle, $ \theta $, in local coordinates. A simulation of a diffuse flux of neutrinos can thus be used to determine the number of detected events from an astrophysical source with the given telescope.
