This topic will consist of discussion of Juno operations post-JOI until end of mission, currently anticipated in Feb 2018.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Thanks, well I had almost three years time to experiment with efb01.
For the distant Jupiter image I'm working completely different from an initial intuitive reality regarding the 3d scenario. In this case, it's sufficient instead to assume Juno staying in the center of a hollow sphere with a large radius, and all objects placed on the surface of this sphere. I've used a by-hand approximation method to find Juno's rotation in terms of interframe delay, essentially a bisection method, working best for swathes where you get Jupiter at the start and at the end of the swath. But since I've used only a very small number of test images, and since there are other uncertain camera parameters, the value isn't optimized over the whole data set. This approach won't work with Jupiter close-by. Then trajectory and Jupiter's shape and rotation need to be modeled. But with the latter approach the transition between Jupiter's shape and infinity gets somewhat tricky. Edit: Yes, I see a clear shadow in 1196-1199. I'll post the cropped images later. |
