<BR>
Let me suggest the following response to the committee’s comment about showing PWA predictions as bands:<BR>
<BR>
</SPAN></FONT><FONT SIZE="2"><FONT FACE="Consolas, Courier New, Courier"><SPAN STYLE='font-size:10pt'>There are a variety of ways to show that there is some spread inherent to PWA predictions that changes with kinematics. The PWA curves in the figures are from Energy-Dependent (ED) PWA. In the case of SAID, these are smooth parameterizations of a set of Energy-Independent (EI) solutions. The latter are made by binning the world's data in W and assigning all measurements within a particular bin to the centroid energy of that bin, even though all of those data were not taken at exactly the same energy. So there is an inherent fuzziness in this PWA process. (BnGa does the reverse: they fit parameters of an ED PWA, and then evaluate consistency by comparing with an EI solution, constructed in the same way as SAID.) It is this fuzziness that is indicated by PWA bands evaluated for the W limits of each bin. (This uncertainty does not reflect that fact that the amplitude is still underdetermined, due to an insufficient number of observables. That can still be large but is quite difficult to evaluate.)<BR>
</SPAN></FONT></FONT><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'> To </SPAN></FONT><FONT SIZE="2"><FONT FACE="Consolas, Courier New, Courier"><SPAN STYLE='font-size:10pt'>help alleviate concerns over misinterpretation of the PWA bands, we have added the following two sentences (somewhere near the end of the first paragraph of section IV),<BR>
“PWA combine results from many experiments at different energies, and this results in varying degrees of sensitivity to energy and angle. This is illustrated in figure 7 by the SAID and BnGa PWA predictions at the limits of the energy bins.”<BR>
<BR>
Then, in the 3rd line of the caption to figure 7, I would change “bands” (used there to refer to the W range) to “bins”; ie. use “bins” for energy and “bands” for PWA, to keep it all straight.<BR>
<BR>
I would think that should do it.<BR>

<BR>
We have received our comments for the K0Y0 paper from the committee consisting of Bill Briscoe, Marco Mirazita, and Gabriel Niculescu.<BR>
Attached to this message are two documents:<BR>
<BR>
1) Their comments with my (our) replies embedded.<BR>
<BR>
2) A revised draft of the paper that implements (almost) all of the suggested changes made by the committee. <BR>
If possible, please have a look at the two documents prior to our meeting on Friday. I am hoping to send these documents (subject to your approval) back to the Ad Hoc committee for their approval.<BR>
<BR>
