O.k. here is the problem:
There are a bunch of points in 3-space and they are supposed to be
scattered around the surface of a sphere. You want to find the
center of the sphere and the radius.
NB: The data are noisy (about 2% of the radius) and only cover a patch
on the sphere.
I think I have a reasonable solution, but maybe someone knows of some
real elegant method?
