There is now PDS-format JunoCam cruise and Earth flyby data available; it's been submitted to the PDS, but MSSS has gone ahead and posted it on their website. I've created an index page to it here. Unlike my usual index pages, there aren't any thumbnails because of the odd nature of JunoCam images, with their long skinny shapes and interleaved framelets. I haven't played much with these data because it's a bit beyond my skill -- I look forward to seeing what any of you can do with it.

The effect in your comparison is indeed larger than I remembered. For the small marble movie images, a misalignment of one or two pixels can be rather obvious.
For PJ08, I've performed calibration runs only for the early approach phase, but with several different sets of assumptions. For the same assumptions used in the above PJ09 calibration run, the best-fit data have been around .002 radians rotation around JunoCam's optical axis. But this might have convoluted unmodeled s/c or camera properties specific to the position of Jupiter in the early approach images. During the first few hours after a s/c op, Juno may oscillate a bit, before it's dampened down to the level of statistical noise. |

During the first few hours after a s/c op, Juno may oscillate a bit... True. If you're using the C kernel, any oscillation should be captured in the kernel. If you're not using the C kernel, then all bets are off. I still find it hard to tell in this whole exchange if people are using the C kernel, and if so, how and when. If there are errors in the angular offsets for Junocam in the I kernel and frames kernel, or if there's spacecraft motion not being captured in the C kernel, I'd like to know about those problems so they can be fixed. -------------------- Disclaimer: This post is based on public information only.
