Figure 1
Normal probability plots for 5000 images. A 5000-image subset of the data was merged using protocol 3. During each step of the parameter refinement, a normal probability plot was generated (a). The rankits (equation 12[link]) are plotted versus the sorted normalized deviations from the mean (equation 11[link]). Each line represents one step during refinement and is colored using a rainbow color map from red (early steps) to blue (late steps). This is a non-gain-corrected data set. (b) Enlargement of the central area of (a) used to compute the slope and offset for initialization of the parameters. (c) As (a) but with a gain-corrected data set, in which each pixel was divided by 25. (d) As (b) for the central area of (c).
