Not that I mean to compare Itokawa to a sausage, just to show you behind the scenes of making the map, along with the map itself, here, rather than continue to clog up the Hayabusa Return to Earth thread.
Here is the map itself, so far along as the pasting in of the mosaic has gone. And here is are two shots of the folded up map, compared with the computer-made model. Note the arrow to one of the "ears." The first try of the map failed to capture the ear, so I replotted the boundary, as seen in the Tracing image. All photos credit: Sara Adkins Studio |

"I'll see what I can find tomorrow."
Phil, [EDIT, after Phil's last post] Oh. Nevermind. Maybe something will turn up in Houston. Can you produce the squares in something approximating the "high contrast" look of the cylindrical map? Can you produce the squares both with and without graticle lines? That way I can get a nice clean cut from the "without" square, and still use the "with" square to lock in the registration. And, if you've time for another request, can you use the Gaskell shape model to check my latitudes on Itokawa's chin? See the pic; the magenta lines are my guesses for the 23.333 and 26.667 latitudes. It's pretty tricky, because of the chin's extreme elongation, to locate where these latitudes emerge at the surface. Can you plot these for the areas I show? Some of my concern here (see the constant-scale natural boundary map) may be from pixel resolution. I had to stretch (enlarge) these squares by a factor of 5 from the cylindrical map. (At the poles, of course, the cylindrical map was way more pixels than I needed.) For most of the rest of the asteroid, the cylindrical map held about as many pixels as the corresponding area on the CSNB map. But under the chin, especially, higher resolution would make for a crisper image than what we've got so far. I've got to get hold of software that'll let me open and work with these digital shape models. Any suggestions? |
