Figure 5
A plot showing the difference between successive iterates as a function of iteration number. The units on the logarithmic vertical are arbitrary; for reference, the lower limit corresponds to the floating-point precision of the computation. Two data sets are shown, with 15 collapsed frames (48 photons per frame) and 200 collapsed frames (623 photons per frame). The sparser data set takes much longer to converge and the slope of the curve in the last few iterations is strongly related to the number of signal photons per frame.
