We took bias sequences (10 bias each) with an incremental time span between each sequence.

This allowed us to verify the effect of "integration" time on bias.

Note that the first bias of each sequence has a saturation pattern that

is proportional to the time span between sequences: 150, 300, 600, 1200s.

With the room made available for light by the spacers and the shutter not light tight the CCD is gathering light.

We can repeat it on 2010 09 21UT now that we used black tape around the spacers space and see if there is improvement.
