Detailed Description

Sample the number of Cherenkov photons to be generated.

This populates the GeneratorDistributionData used by the CherenkovGenerator to generate optical photons using post-step and cached pre-step data.

The number of photons is sampled from a Poisson distribution with a mean

\[ \langle n \rangle = \ell_\text{step} \difd{N}{x} \]

where \( \ell_\text{step} \) is the step length.

Collect the distribution data needed to sample Cherenkov photons.

If no photons are sampled an empty object is returned.
