Distribution of counting measurements
If the average number of counts in each sample is <N> (if an integer then only by accident) then the probability of a particular count being N (always an integer) is
p(N) = Exp(-<N>) <N>N/N!
called the “Poisson Distribution”
The standard deviation of p(N) is Sqrt(<N>)
