Voting for Perijove 06 started yesterday, and it will last for another almost 7 days.
This time, I'm not quite free of bias, since I'm interested in an extension of the polar time-lapse sequence, especially in a coverage of the north and south polar FFRs and the presumed edge of the respective polar haze disks. I think - well, I'm rather certain - that it's possible to infer short-time dynamics of the FFRs, and of the vortices near the edge of the haze disk. Due to the expected good contact to Earth during the PJ-6 pass we have a good chance to obtain overlapping images of these regions. More in the discussion section on the missionjuno site. Of course, there are other interesting targets, too; see Glenn's and John Rogers' (Philosophia-47) comments. A full latitude coverage would allow for a pole-to-pole animation. |

I've noticed this before, but I didn't yet narrow it down to a candidate cause as good as yours. Before the decompanding table became available, I've run an empirical / statistical analysis on the red/green and blue/green quotients as a function of the green value, and found smoothed curves where the decompanding function has kinks between linear fragments. I attributed this to a smoothing effect caused by my analysis method. But with your observation, it might be worth to run a new analysis with formally decompanded values. I did so when I used the decompanding table for the first time, and it looked so much better than before, that I was happy, and didn't persue this any further.
When preparing for my EPSC talk about Jupiter's reflectance function (finally accepted!), and haze, I'll take another very close look at the effect of solar incidence angle and emission angle on brightness and color. I'd think, that any errors in the decompanding function should show up as anomalies. Btw, Seán, your processing tests are really very! promising. |
