Re: GenCon 1989

	One item that should be brought to the Digest Group's attention
is that the star does *not* go in the *center* of an elliptical orbit!
Rather, it goes at one of the *foci*. Among other things, this means
that closest approach is *opposite* farthest seperation, not 90 degrees
away from it.

I'll be putting together a letter to them about this, but they need to
know they goofed *soon*!

In case you are wondering where this comes from, take a long hard look
at the diagram on page 65 of _World Builder's Handbook_.

As for the Imperial Atlas data, it would appear that some (most?) of it
will be available early next year in machine readable format. See the
ad on the last page of the handbook.
