which show a flat read noise response with regard to ISO, more or less.

There is something wrong with sensorgen's numbers. He is attempting to fit DXOmark's data, but somehow comes up with different values than I do. My fit to DXOmark's data is exact- which shows that they plotting a fit themselves instead of raw data. Since my fit to the DXOmark plot data is exact, I think sensorgen must be doing something wrong to get different values.
