There are slightly fewer events accepted with the confidence level cut (CLC) used in kin. fitting, even with a modest one that I chose of 5%.

This is a very nice work all together Frank, it would be nice to<br>
quantify how error bars are modified for DVCS. Results are indeed<br>
consistent, but do we have better error bars? This seems to be the<br>
case for some points, but it would be better to have a general<br>
statement on the topic.<br>
<br>
On a side note, do you, or any one else, know what is the publication<br>
plan for this study? Since I did not attend the meetings for a while I<br>
am not completely up to date on this.<br>
<br>
Best,<br>

It has the kin. fit formalism, how it's applied to DVCS and DVMP, and how it compares to exclusivity cuts for event selection. I would like to submit to a committee and see where it goes from there.<br>
