Some of the images have been posted on missionjuno.
You will immediately notice that there is something weird about them. Yes, we know about this, and I'll say more about it when I can. In the meantime, anything people can do to process them would be appreciated. I've had some success using https://github.com/chunglabmit/pystripe -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Destriping the images seems to be trivial. I've had fairly good success using code based on a description of what the ISIS3 dstripe application does but I haven't tried pystripe yet (mentioned in the first post of this thread). The resulting red and green images don't look too bad. If the situation doesn't get worse before or during PJ57 the Io images are going to be very interesting despite this problem. A very quick-and-dirty destriped version from image PJ56_132 (can be improved, in particular I'm treating this as a single image instead of treating each framelet as an individual image):
A question for Mike (if you cannot answer it I understand): Is it safe for me to assume that the images got corrupted before companding or is it possible that they got corrupted during/after companding? I'm pretty sure it was before companding, meaning that I should decompand the images before I destripe and subtract the background but I want to be sure. |
