Thankyou Michael!

It is good to know which direction to take. I am working on a script.

I was actually looking at your first link earlier this evening.

I'll study your solution, and incorporate it in my script.

So far I have had to correct several dozen of my programming errors, and am beginning to get a little better at using the several varieties of "points".
The reference paper so far has one +/- sign error, but may have another...Still a ways to go on deciphering the math...
