CaSSIS does have similar functionality with tgocassisstitch (and tgocassisunstitch). But no, we don’t use it either. The only place where we might want to use it is during bundle adjustment but we just make use observations mode in jigsaw to ensure that framelets taken simultaneously are adjusted together.

A good "Introduction to JunoCam Imaging" thread on twitter: https://twitter.com/akaschs/status/1576220654801936384

OK, so I just wrote up a new JunoCam processing pipeline. I wrote it in Rust as a dedicated processing package which uses a much less complex method than what I have been doing. I'm mainly just using the CK kernels to determine spacecraft rotation in order to restitch the framelets together (leading to the primary limitation that it doesn't yet account for spacecraft motion). It does dark/flat calibration, hot pixel correction, and blemish infill correction. I tried to make it as cross-platform as possible, but I've only so far tested it in Linux (Kubuntu 22.04 & Ubuntu 22.04 in WSL, specifically). So far, I've only written it as a command line tool, but it probably wouldn't be too hard to add a GUI. I expect it to be a somewhat buggy and imperfect in it's current state and only supports RGB images, though I do plan to add methane or other single-channel image options.

I put it up on GitHub if anyone wants to check it out: https://github.com/kmgill/junocam_processing

It does OK

At perijove, it shows it's limitation in respect to spacecraft motion, but this should be correctable.

One thing that kinda of went by unnoticed by me was that data from the SRU is finally trickling into the PDS: https://pds-imaging.jpl.nasa.gov/data/juno/JNOSRU_0001/

Only one orbit so far (36), but at least the SIS is out now. once orbit 34 is released, I’ll take a look at writing a script that can at least allow for adding geometry backplanes so you can reproject them in ISIS using nomap2map.
