I think that this plot might be dominated by pixel-to-pixel variations, rather than the noise in an individual pixel… wouldn’t you need to normalise each image by a very good flat field, so remove pixel-to-pixel variations, and then measure the scatter in the square regions — this now being ascribed to the Poisson scatter?
Compare the non-Poissonicity foundhere to newer results on the CCD camera at MLO:
