This is the same effect that Peter mentions although it is normally seen with binning on the KAF8300 and the lines are typically shorter. I wonder whether you have the gain cranked too high? It should be set so that a full well results in an ADU value no larger than the maximum 16-bit unsigned value of 65355.

Cheers,
Rick.

Hi Rick,
the gain of 5 gives me full well depth at 56,000.
Maybe I should ask Theo at gamma?

cheers
Allan
