Perhaps Brian just needs to explicitly state "published data". I do not consider unpublished data that happens to have been shown at a conference as belonging to the world data base. A lot stuff gets shown at conferences that will, for very good reason, never be published.<br>
<br>
Just my 2 cents worth.<br>
<br>
Take care,<br>

Be careful, Mainz and Bonn are running with polarized beam, target and<br>
recoil for the last year. The data exist and are being analyzed as we speak.<br>
Currently, we are taking double polarization using polarized deuterium to<br>
provide the polarized neutron. Double polarization parameters from both<br>
places have been shown at conferences. I would word things a little<br>
differently.<br>

Hi Brian:<br>
<br>
Your statement that "...there are no previous measurements for double<br>
polarization observables" desperately needs to be preceded by a<br>
statement of exactly what process you're talking about. CLAS has<br>
published several double polarization observables in multiple reactions<br>
over the years, as have (I suspect) several other facilities. I would<br>
suggest rewording the second sentence as<br>
<br>
"In the eta photoproduction process on the proton, there are relatively<br>
few single polarization measurements, compared to unpolarized<br>
differential cross section measurements, and no double polarization<br>
measurements." Some wordsmithing is still needed there.<br>
