A few replies in one.
Bob, you'll have to wait a while! Big_Gazza (if that is your real name), the Vega images you showed are heavily over-processed. The apparent fine detail on the nucleus is largely noise. Some of the more subtle and larger features might be real, but the smaller textures are false. Also, you can't trust that the edges of the outlines are the real shape of the limb. and Tayfun Öner, whose work with maps is always very good - the images I'm interested are the last few images in the sequence, showing a small area near the "small end" of the nucleus. I have a hunch more can be done with them. Don't know when I'll get to it though. Phil -------------------- ... because the Solar System ain't gonna map itself.
