Before the T9 data came down, I got a little bored, and played around with some Voyager data of Ariel. The mosaic (oft produced) I generated is below. Again, this mosaic has been produced by a number of folks on the net, so this isn't really new, but I thought I would get this product out there anyway. I stretched the image such that only a few crater rims would have a DN=255 (other mosaics boost the contrast a bit too much, overexposing the ejecta around Melusine, for example. I also ran this image through a high pass filter, sharpening the image.
Enjoy! -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Steve, I think the image in post 5 of this thread might be a little clearer than the one you used. And these two (almost the same as each other) fill in the gap.
I'm especially pleased to see the nightside detail added to your map - certainly a first in the history of planetary cartography (for Ariel, I mean). Phil It's very hard to get a good image out of the dark side views. Ted has done a great job. I tackled it as well, with this as one version of my efforts: It could extend that dark side coverage, including the apparent extension of the canyon area. If only the Voyager imaging team had recognized this possibility at the time and planned for it! We could have had good images of another 20% or more of several of these moons. Phil -------------------- ... because the Solar System ain't gonna map itself.
