The parameters relating to the shape of the primary and secondary electron distributions, as well as an additional Gaussian noise factor were allowed to vary. A fit with these degrees of freedom was performed on three distributions from drastically different light levels (corresponding to roughly 64, 530 and 973 primary detected photons.) The following model parameters produced reasonably good fits (''χ''<sup>2</sup><2.0) for all three distributions.
