Read-out noise

Noise measured in bias frames with 1*1 binning, mpp+ mode, amounts to:

While the values above were obtained for 1 by 1 pixel binning, read out at higher binning is disturbed by a pattern visible in low exposure frames. By careful reduction it may be possible to eliminate this pattern, but if the pattern is left uncorrected, the resulting high gain read-out noise becomes:

The mpp- mode seems to result in higher read-out noise, e.g. Amplifier A, high gain, mpp-, 1*1 binning has 7.5 e RON.
