Re: a9 mean row sigmas by color plane

Well that's interesting!

In truth, these noise level differences aren't all that significant, but it sure is an interesting set of shapes. Blue seems to have some averaging going on, but I think the slopes on G1 and G2 are actually more interesting (especially given R doesn't have it).

I would have guessed that the increase with row number was due to readout ordering, but that makes little sense given converters on chip and even less sense if B and R aren't affected.  Do you have an explanation in mind?
