just for interest, dug up a composite image that shows what goes on.
the leftmost panel shows a group of warm pixels at gain 100, time 120s.
the next panel shows the same group at 300s - same group, just 2.5x brighter.
the next panel shows the same pixels at 600 seconds - 2x brighter again, but the hottest 5 pixels have simply disappeared.
the final panel at gain 200, shows that all but dimmest 4 of the original group of 16 warm pixels have been "disappeared".
If a hot pixel happens to be near the threshold value, it can flick in and out of existence from frame to frame, depending on read noise. cheers ray
