Pictures of the VIMS data from each flyby from the nominal mission are in a paper now in press from Planetary and Space Science (also available from my website). This is basically intended to be a guide to what VIMS observations are available from each flyby: the territory covered, resolution, phase angles, etc. Thought you all might be interested, as I do think that many of the pictures are totally awesome. Objectively speaking

Fantastic... thanks Jason!!!!

Rather than opening a new topic, I figure this is a good enough place to post. Emily's neat writeup on phase angles and comparison shots made me do a similar thing for Titan using VIMS data. Here's an animation of well-exposed and mostly global (a few limb cuts here and there) Titan shots that are currently available at the PDS.

Average distance was about 200 000 km and all 16 frames were scaled to the same size and magnified roughly 4x from VIMS pixel scale. Phase angle runs from 18 deg through 166 deg where apparently light starts to leak into the visual channel. Click the image below to animate.


I optimized the brightness for the low phase appearance because most higher phase shots I got are saturated in certain channels, otherwise it would create a pink appearance in areas where they're whited-out above. Also, the same caveat applies as in Emily's case - the subspacecraft point jumps all over the place so there are inconsistencies in hemispheric banding, haze layers, etc.

Might as well throw in another short VIMS Titan flyby animation for fun, taken on approach during T45.

Very cool, man -- I like it! I see some changes, though, I wonder if phase angle changes and changes through time are both going on at the same time, there.

I should think so, Jason. For one, you can really see how the hemispheric banding jumps around and changes orientation in the lower phase frames. Mind you, there could also be calibration issues on my part involved, but overall the color seems pretty consistent.
