Greg,

I checked my bias master. There is a slight difference in average value from the first rows to the last rows but it is tiny - about 0.015 ADU compared to a bias value of 1220 ADU. This is equivalent to about 1.5 seconds of dark current at -30C. That could be about how long it takes to download the data from the sensor into the RAM buffer on the camera.

Cheers,
Rick.
