Special notes are below.
I hope you can scan the attached before Friday's final teleconf. Rather than a section on choosing an Option, I have imbedded all the thoughts in the first part of each Option's definition. I studied the FEMP 2.2 as supplied by Steve and used what I could. I put the relevant changes to Section 3 at the front of the attached file. Also describe qualitatively the expected impact of factors affecting the accuracy of results but which cannot be quantified.
