Overscan correction can be improved. Specifically, some systems have sharp discontinuities in the bias section.
Turn on bias-jump fix for all CCDs
Improve overscan correction for DECam raw data
What improvements does this ticket involve?
The sharp discontinuities in DECam are supposed to have been solved by DM-4366 and DM-5265.
We are closing as "won't fix'. DECam is presently the only camera that needs this, and it has a solution. It is hard to write a general solution without more examples of the problem (other cameras that have discontinuities).
