Galileo's Moons: 4 at 400, Serious Satellite Video Options

[DrShank]

I have posted 4 new videos on http://stereomoons.blogspot.com
They show each of the 4 Galilean satellites from a topographic perspective.
Each moon is very different in character and this is reflected in the content of the videos.
These are added to the growing collection which started with the Saturnian, Uranian and Neptunian
satellites and add to several already released for Europa. These are also featured in the blog
and the videos themselves are posted on YouTube - http://www.youtube.com/galsat400 -
as part of the ongoing celebration of Galileo's 400 year anniversary. More will be added
over then next few week. I attach some stills from these animations, the details for
which can be found at blogspot!

I've thoroughly enjoyed viewing these images and movies. I'd like to ask a very basic question in the 'probably been answered before but I can't find it' category. How much vertical exaggeration are you using here? Is it a constant factor for all the images? I'm trying to find out what are the actual gradients on Tohil Mons (for example). I've looked in quite a number of places but haven't been able to find a side view or cross section with scales given or an actual slope estimate anywhere. I did find one schematic cross section on p 322(EDIT just looked again and can't find it. Maybe I got the page number wrong. I notice you get a different selection of pages every time you open that link.) here:

but I don't know if that's at a one-to-one scale either.

Which is Tohil most like?
