Neat!  TSSP should easily be adaptable to the flat configuration.

I want to make a flat secondary too to directly compare results and verify.
 E-Tesla needs to have its results checked against the real case.  It has
too many things that can go wrong (like the programmer).  I would never
trust a result from it that was not verified.  I have tried changing the
Guassean surface before and have always gone back to the sphere!  If it
works, computer time is of zero concern there.

Ok, I'll have to think on that more *;-)

I am collecting parts to construct a flat secondary.  I am not sure "how"
yet but I guess I will figure it out.  Dave went through a bunch of wire
and iterations before he could do it so I am sure it will be a challenge.
Dave kindly offers to do the work for $75 (I think he said it takes 8
hours!!) but I want to learn how too.

Cheers,
