Juno perijove 9, October 24, 2017, near solar conjunction Options

[Gerald]

It's time to start a new topic for Juno's Perijove-09.
Due to solar conjunction, data downlink is delayed several days, but things appear to look good thus far.
Data downlink started on October 31, and if everything continues well, it should be a matter of a few days, at most, until the majority of the raw Perijove-09 images will become available. Due to the incremented available storage for JunoCam, we may get a sufficient coverage to render a pole to pole -- well, almost pole to pole -- fly-over reconstruction, despite the difficult communication near solar conjunction. I'll have a try at least, over the next few weeks.

In order to remove most of the greenish cast, I've been using 0.88 for red since PJ-06 for enhanced images. But this might undergo another refinement later.

In general, I'm not sure, whether there is a fixed "how to". It depends on your purpose. I've written almost 10 MB of code for various purposes of JunoCam image processing and related tasks, almost everything from scratch. Might be the code could be shortened to 5 MB with sufficient effort in "refactoring", but I've still a long list of TBDs after four years of development. I might double the code next year in order to cover some of the items on the (ambitious) list.
I'm interested in developing and understanding all technical detail about camera calibration, processing, data reduction, evaluation, and beyond, independent of possibly existing partial solutions, but that's probably not the recommended way for people, who just like to create beautiful images, nor for professionals who need to reduce specific project costs and risks.
The semantics of the code overlaps with that of NAIF/SPICE and ISIS3. So, if you are happy with "the standard", you might consider to base your work on these libraries and tool sets. The JunoCam extension for ISIS3 is work in progress since quite a while, and might be released next year, for those who are used to work with ISIS3 in a UNIX environment.

Regarding threads, I guess, that Candy would be happy to learn about possible extensions of the missionjuno website. One of her primary objectives is "Science in a Fishbowl", as far as that's possible without running into science publication or privacy issues. "Evaluating JunoCam images with ISIS3" might become one of the considered topics.

The JunoCam extension for ISIS3 is work in progress since quite a while...

There is a beta version of ISIS3 that supports Junocam. I was told not to distribute it "outside the team" but since everyone here is on the Junocam team I'm not sure what that means. If you're interested PM me with details about which platform you want it for -- it's available for the 64-bit version of Mac OSX 10.11 and various 64-bit flavors of Linux. It's worth noting that ISIS3 has a very very steep learning curve so this is not something you should ask for casually -- you might start by downloading the production version of ISIS3 to see if you can figure out how to use it on a simpler case.

As for a unified thread about Junocam processing -- I'm not sure there's a unified thread about anything on UMSF, but it's a good idea in theory. The thread over in http://www.unmannedspaceflight.com/index.php?showtopic=8353 is an example, perhaps overly specific to the standard SPICE formalism. Some amateurs have documented their workflows in fair detail, some have not (which is fine) -- I am always curious to see how people are doing what they are doing.

...

I've access to the beta, in principle, but no system it is running on. A member of USGS considered providing a VM. This would simplify installation "infinitely".
But I've loads of other tasks. So, I may not be the first one to test the ISIS3 extension for JunoCam.

@Jay, you can really learn lots of interesting things from JunoCam image processing, once you are ready to dive into this adventure.
