      Description

      Whilst looking at an individual spot from the CBP on DECam I noticed a weird feature, and upon further investigation, several more, though these were very hard to see.

      This ticket is to investigate what image processing techniques will make these hard-to-see features pop out so that they can be examined more closely.

          Looking like some nice results were obtain for feature enhancements.

          Will dump before and after images in a Powerpoint/Keynote.

          Initial results posted, but discussion has resulted in one more thing to do:

          By comparing the pattern of these features across different CBP spots on the focal plane we should be able to determine whether these are dust spots in the CBP system, which people who know about this stuff seemed to think plausible/likely from their appearance.

          Will perform this comparison, then post results here and close ticket.

          (I don't think this can be in review while there is still more to come.)

          Merlin Fisher-Levine — Am I correct in assuming that you're not working any further on this at the moment?

          Yes, that is correct. Will be easier to pick this up when I resume looking at DECam stuff in general, i.e. after the next 3-month unit (I forget the name for them).

          I don't believe there's any more work coming on this ticket. When you return to looking at the CBP data, we'll make a new plan to cover your new activities. Shutting this down.
