All, Thank you all for your comments. I am including changes requested by Arpad, Bob, and David. I suggest that IBIS-ATM should first consider the accuracy of this draft vs 123.3 and the changes suggested by Bob and David. Once these corrections are agreed to, the Editorial committee should have their way with it, and then a final review by the ATM committee which would re-submit it to the Open Forum.
