(a) Class averages randomly extracted from the total of 3000. High-contrast class averages are associated with good views of the worm haemoglobin, whereas low-contrast class averages are associated with atypical false-positive particle detections. (b) The histogram of standard deviations of 3000 class averages (205 764 particles) reveals a bimodal distribution in which virtually all remaining false positives land in low-contrast class averages.
