How I set These Up

Hi Phil,

I don't think interpolating between sets of osculating elements is a thing. You'd have to assume that everything changed linearly and that none of the elements was coupled heavily to the others. This is why I went straight to an n-body calculation... its the only correct way to do your "interpolation." Its an interesting idea, and maybe there is a paper out there on it, but as I said, I think three sets of elements is fine in most cases, and adding more near close approach is a better solution.
