Figure 4
The difference between the estimated background value either with no outlier handling or with the GLM algorithm, and the median (i.e. most robust) background estimate for Bragg reflections with large indices of dispersion in the surrounding background pixels (an indication of the presence of pixel outliers) for (a) thaumatin, (b) DNA and (c) thermolysin. The horizontal black lines in each plot are at ln(2) and -1/3; for a Poisson distribution, the bounds on the median are [\lambda - \ln(2) \le {\rm median} \,\lt\, \lambda + 1/3] (Choi, 1994BB3).
