Richard,

</div>
<div class="">Here are some comments.</div>
<div class=""><br class="">
</div>
<div class="">- line 28, this is not a true statement. The threshold for open charm production is higher than the threshold of direct J/psi production. The most of the phenomenology behind gGFFs is near direct production threshold.<br class="">
<div>- line 38, remove “p” after “J/\psi’ </div>
<div>- line 67, “detect and identify neutrals and electrons”.</div>
<div>- line 86, are you using the same MLA that Mariana worked on? I believe she does not have HTCC photoelectrons in the classifier.</div>
<div>- line 95, is this correct? I believe the default is the first layer of the stack (PCal, ECIn, and ECOut)</div>
<div>- line 103, will be good to add the section formula (four vectors) and how Q2 is calculated. </div>
<div>- line 103, why not just “the mass of missing particle”, remove “invariant" </div>
<div>- What are Q2 and MM cut values?</div>
<div>- line 139, the second sentence of this paragraph seems redundant </div>
<div>- line 147, some thing is wrong with this sentence, add “shown" before “in” at the end of the line.</div>
<div>- I agree with Bryan about your figure 4. You can just say that these results are consistent with proton data from CLAS12 and GlueX, without showing a comparison plot.</div>

As you may know, Patrick asked for results from RG-B that he can show at the<span class="Apple-converted-space"> </span><span style="background-color: rgb(255, 255, 255);" class=""><a href="https://indico.fnal.gov/event/62069/" target="_blank" id="OWA1e0f7048-16ba-cd2f-d24e-7beacee59429" class="OWAAutoLink" title="https://indico.fnal.gov/event/62069/" rel="noopener noreferrer" data-auth="NotApplicable" data-linkindex="0" style="margin: 0px; background-color: rgb(255, 255, 255); text-align: left;">International

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<span class="Apple-converted-space"> </span><b class="">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>
