Perijove 40 data is starting to be posted. I'm getting some weird timing issues with Europa, though.




Jupiter - PJ40-7

IIRC, every time before when somebody has reported "weird results" it's been because of out-of-date kernels or something like that. Please list your complete kernel set and I'll take a look when I get a chance.

We don't typically do the timing corrections until later but FWIW I don't see anything especially noteworthy in our processing so far.

I'll post a kernel list tomorrow (time to go to sleep now in my time zone). However, I suspect signs of these "weird results" can also be seen in the map projected color images posted together with the raw images at the missionjuno website. Below is a modified version of PJ40_11. In contrast, e.g. the PJ39 images are not like this.

I'm not seeing a problem. My limb fit came up with a -0.00876s start time adjustment for PJ40_11 (shown below with limb marks on Jupiter and Io.)
