I would like to congratulate Andrew Bennett for correctly solving the
puzzle. Below is his complete solution:

Note that this is a very deceptive prblem. When random data is taken which
has a narrow distribution, it appears to be just fine. That is because the
data is random and it does not care that the bytes are mixed up. It still
gives a nice plot. It is only when the total spread of the distribution
exceeds 256 that funny things start to happen. First there are "side lobes"
spaced by 256 counts. For a broad enough distribution, the "Sears Tower"
shape with 256 counts between steps occurs. This is devious, and leads one
to search for temperature effects - the problem first appeard when I raised
the temperature to study the dark current.
