A lot has happened and it seemed like a good time to start a new post. We will be staying in 53 day orbits until the project has a full understanding of the risks that may or may not be associated with reducing the orbit period to 14 days per our previous plan.

Synopsis of Perijove-03 subset:
Larger subset of larger versions. For illumniation adjustment, I've divided the decompanded colors by a polynomial of degree 5 of the cosines of the solar incidence and emission angle, resulting in a sum of 21 items. The polynomial is a manually slightly modified relative best-fit within a range of cosines of the two mentioned angles that avoids proximity to limb and terminator. The best-fit is based on a set of about one million Monte-Carlo samples taken from all TDI-2 Perijove-06 images without moon shadows. For this sequence, I've used the polyomial of the green filter for all three color bands, hence didn't apply illumination-dependent white-balancing. I modified the best fit in order to get some shading instead of a flat appearence, and in order to avoid a non-intuitive bright terminator. The PJ-03 images have been a test, whether the same polynomial can be applied globally for any perijove and image. The ad-hoc heuristics I've used before for PJ-06 and PJ-07 is less suitable for PJ-03 due to the proximity of the terminator for the very close-ups. These images aren't yet submitted to missionjuno. I may submit the fully resolved version of the synopsis, but I'll wait with the individual images, until a decision is made of whether a separate section will be defined on the site, for this kind of products. I'll try to revise PJ-04 and PJ-05 in a similar way, before raw PJ-08 images will be available via missionjuno. |
