What the tone curve represents is the relationship between the
12-bit raw value and the exposure (in 1/2 stop steps). I plot the
mode (the histogram cell with the largest value).

The only thing I don't understand is that, since this is done from raw data without any processing, why the presumably linear raw values don't change linearily with exposure. Normally if a particular channel is close to clipping to level 4095 at say exposure 8, then at half that exposure the same channel should be about 2048 or half the value. I don't seem to see that in your charts unless I'm looking at them correctly?
