The estimates of photoemission rate correlations that are obtained by clipped, e.g., one-bit, correlation techniques are in general distorted by the clipping, unless scaling techniques are used. It is shown that the Poisson statistics of photoemission processes are such that the processes are inherently self-scaling when the range of signal fluctuations is contained in the range of inherent noise fluctuations. Self-scaling occurs, for example, when the total mean emission rate is large compared with the time varying signal rate. It permits clipped correlation to be used without distortion.
