Consider a CCD detector whose characteristics we want to investigate. Assume that for the kth pixel the rate of photoelectron acquisition is 500 photoelectrons per second from the sample, 30 photoelectrons per second from the background, and 0.1 electrons per second from the dark current. Further assume that the readout noise is characterized by a mean (offset) of 100 DU and a standard deviation of 8 DU. The electron-count-to-DU conversion factor is given by c = 0.3 DU/electron.
