Ok I reran Dead/Hot Pixel test

On my first remap i had 512 hot pixels as wel. After cooling the camera for some time the remap gave just 276 hotpixels.

What do you mean by cooling, and aren't you afraid that this is not a typical setup, as in most cases you cannot cool the CCD during a picture taking session?

If you lower the threshold in the deadpixeltest program from 60 to 0 you'll still see some pixels giving a very small output, but not visible.

I lowered the threshold by 10's down to 10, then @ 5 I had three hot pixels that were not visible in the review pane.

Perhaps the remaping routine in the camera can accept a threshold value below which a pixel will not be remapped.

Or maybe it would be nice to know what the threshold is for all the mapped pixels. But your idea would allow you to not remap anything you couldn't see anyway.
