I've completely rebuild my script correction hot dead columns / cold / that I developed at the request of Nicolas FLI for its cameras.
With the classic algorithm, we know a fixed column but not a double. This script does. then we realized that the 2nd, (sometime first too ) is not dead but just cold (adu slightly lower), I have therefore found an algorithm that can rebuild these cold or hot columns enhancing lost ADU .
This also applies to a single column, because it avoids the averaged replaced by a simple algorithm.
In this example, the first colone is dead, but the 2nd is just cold, it was recovered.
