Hmmm...a very weak green light leak above the physical top of the sensor? Can you check if the G1/G2 mean values drift up with the G1/G2 stdev mean? That would prove/disprove that theory.

Here are both sets for the a7RIII. I'll have to go back and run the a9 again.

Thanks. I was only half-serious about the light leak So the mean for R+G drifts up very slightly (by ~0.05), whereas G1/G2 drifts up by twice as much (~0.10). These quantities are so small it has to be something very subtle. These graphs are for the stacked frames right?

Right.

Is the trend the same for an individual blackframe?

Haven’t tested that  but I think it’ll be too noisy to tell much.
