interesting thread.

FWIW, the bias on my 694 also varies with temperature - not massively, but enough to matter - the main effect is an increase in the gradient. Read noise seems to be almost independent of temperature (I checked at 0, -5 and -15).

Two measurements of bias at -15 and separated by a year gave essentially the same result, apart from a few additional warm pixels (this chip seems to add 1-2 extra noticeable warm pixels a month).
