Hi Rob,

Since our read noise is not much higher than that we got with the UR black-box
drive electronics, I see the failure of Fowler-reduction as our main impediment
to improved performance.

F1/F8 noise ratio = 2.3 for black-box electronics

sqroot(8) = 2.8, best possible improvement

F1/F8 = 1.9	1.92	2.44	2.03	2.42	2.38	2.47	2.18
Average 2.22 for the gain of x4.

For the gains of 11.3 and 16, the average F1/F8 noise ratio was 2.0

So the overall ASIC average is 2.1, which is lower than 2.3, but not by much.

We'll try your new Fowler software soon.

Bill
