Figure 3
An example of significant pile-up corresponding to a photon rate of 2λτ = 1, where 2τ is the signal decay time of the analog signal from 1 to 0. Note the resemblance to a random walk, resulting in an apparent baseline shift and the complete breakdown of counting over large stretches of time.
