Changing the sample value of Red and Blue channels affects 8 pixels, whereas green only 4

There are two independent green channels, and each is treated exactly as the red and blue channels are. Re-read the array descriptions in my original post.

Why treat i as two though in the processing? G1 and G2 are direct measurements, why make G2's output a function of G1? Is there a presumption that G1 being hot will affect the sensitivity of G2? Or that the processing is done after a read of a discrete channel? Something like :

G1=> processing=> buffer
G2=> processing=> buffer
B => processing=> buffer
R => processing=> buffer

Then integrate G1,G2,B,R into a serialized raw??

Make more sense to treat

[G1] [? ][G1]
[? ] [G2][? ]
[G1] [? ][G1]

as just:

[G][? ][G]
[? ][G][? ]
[G][? ][G]

So how do you see this now per the D7000

....Opps, meant to quote this one.
