Juno perijoves 2 and 3, October 19 and December 11, 2016 Options

[Gerald]

The anticyclone in PJ-03, #107, is called NN-LRS-1, North-North-Little Red Spot-1, see post #73. It was imaged again during Perijove-07, the perijove with the close-up images of the Great Red Spot.

Seem hard to imagine you improving on your previous versions---but you have. I like the subtle change in the color palette. Blues and oranges nicely saturated, but white terminator and other whites have more punch. Thanks for all the creativity you share.

[Sean]

Thanks Floyd... the truth is for a couple of perijoves I was making images on a laptop with a terrible screen and a very messed up color profile - what I made on screen is not what people saw on their browser. I always wanted to revisit these older shots with a calibrated color space in tow.

[Bjorn Jonsson]

I recently decided to take a look at data from the early perijoves when my JunoCam processing pipeline didn't work as well as it does now (or not at all ;-). In fact it's striking to see the big improvement in image quality from everyone here processing JunoCam images when early images from e.g. PJ3 are compared to the recent ones. For example I processed a few PJ4 and PJ5 images when they were released but now I want to reprocess them. But first I decided to process something I haven't processed earlier: PJ3 images.

This is image PJ3_114 which shows the SEB west of the Great Red Spot.

Approximately true color/contrast:



Enhanced versions:




Lots of cloud shadows and vertical relief are visible, especially in the 'central' image (the one where the limb isn't visible). The solar elevation angle is low in these images - in the early perijoves, closest approach occurred much closer to the terminator than later in the mission (at the time of this writing perijove 20 is the most recent perijove). The color coded image below shows the solar elevation angle in one of the above images. In contrast, the subsolar point is visible in some of the PJ20 images.



Below are details from the first true color/contrast image above enlarged by a factor of 3. The image shows Jupiter's horizon near the evening terminator. Jupiter's bright and blue evening sky is clearly visible at the limb. In the right half of the image there are also possible hints of a slightly more reddish color at lower altitudes than the blue color. This is probably a real feature although a processing artifact cannot be completely ruled out. I have processed a number of JunoCam images where Jupiter's sky is visible at the limb. Of these images, this is probably the one that best shows the Jovian sky.

Feel like I should be cross correlating the framelets to line them up better.

Feel like I should be cross correlating the framelets to line them up better.

They look pretty good to me. Shouldn't need to cross correlate within a single single image.

The top edge of the second image looks a little bit off, it makes me think there's some close in phase noise. I feel like just a bit of offset makes the image less clear.

There is also clearly some misalignment far from the limb that can be seen by 'blinking' the red/green/blue channels rapidly in high contrast areas. The misalignment should be smaller. One important issue is that the x (sample) of the optical axis is *not* at the center (i.e. x=824) in the framelets. Depending on how you are creating these images this may be of importance but I'm not sure it's enough to cause all of the misalignment (in particular not the misalignment near the center of your images).
