OFF-QUESTION: How big is an Alderson point?

Phil might be the best one to answer this, but in case it has been
discussed 
before, I thought I would toss it out publically; while it is lanbelled
"off-
topic", I think the gaming implications for _Full Thrust_ are pretty
darn 
clear.

Just how big is an Alderson point?  

I'm asking because it has a tremendous impact on how you protect a
system.  If 
the points are small, then fixed defenses a la _Starfire_ can turn every

hostile warp assault into a buzz saw.  

_Starfire_ warp points, IIRC, are extremely small, with some being so
small as 
to limit the size of vessels that may transit them.  McCollum's
foldspace 
points appear to be bigger, but still small enough that fixed defenses
or a 
fleet can opretty much get off an immediate shot against anyone coming
out of 
a foldspace jump.

I don't remember seeing this in the CoDo universe.  IIRC, the only
defenses we 
really see are mobile, and they consist of 1) the _Defiant_ off New
Chicago, 
and 2) the Crazy Eddie squadron inside the supergiant.	The latter is
clearly 
a special case (presumably the outcoimg ships are pretty disoriented by 
appearing in a sun), and the former, if memory serves, involved the
captain 
lamenting that the _MacArthur_ appeared so close.

Any help appreciated!
