Hi Richard
<div><br>
</div>
<div>The note looks good but I would not include the RG-A and GlueX comparison in the note. It really should just be what is intended to be released. </div>
<div><br>
</div>
<div>I agree that you will probably be asked and you can answer, but this release note and release meeting is not the place to discuss detailed comparisons of a work that is still in progress. </div>
<div><br>
</div>
<div>The message should be internal consistency within RG-B and the first extraction form the neutron, plot 1.</div>
<div><br>
</div>
<div>Cheers</div>
<div>Bryan </div>

As you may know, Patrick asked for results from RG-B that he can show at the <span style="background-color: rgb(255, 255, 255);">

Maxime asked me to present the note at the DWPG tomorrow. Sorry for the short notice in having a look over the note, I was also only asked to do this yesterday! I don't think there's anything especially new or controversial so please don't feel like you have
to review this in a great amount of detail.</div>

For convenience, I've attached the two main plots. First the cross section in AU for J/psi produced on proton and neutron. This has been updated with all three available RG-B datasets, and contains the same information as the previous plot that I circulated.</div>

Second a comparison between RG-A, RG-B and Gluex. This is <b>not</b> intended for release, and is clearly marked as such in the plot and in the note. The reason why I included it in the note is that I assume one of the first questions I will get is on the consistency
with RG-A. As my analysis is not as far along as Pierre's, and in order to make a sensible comparison to RG-A, I used the same radiative corrections and normalisation that Pierre extracted for the RG-A analysis. As you can see, there is a relatively good agreement
between RG-A and RG-B which shows consistency between the analyses. I wasn't sure if this would be appropriate in the note, so please let me know if you think I should remove this and I will do so.</div>
