Hi Tyler,<br>
<br>
Very good slides, it is ready to go.<br>
Few minor comments:<br>
1) on slide #8, "... additional decay particles ..." better "... recoil<br>
nuclei ..."<br>
2) slide #12, Summary,<br>
3th bullet, no need for "... our ..."<br>
4th bullet, better something like this "... the second run is<br>
scheduled ..."<br>
5th bullet, no need for this bullet.<br>
3) I did not check the GlueX requirement for the acknowledgments but<br>
I think if you bring the NSF part in the summary, just bellow the<br>
main text, that would be the standard way and visible (we need that).<br>
<br>
Thanks,<br>
Ashot<br>
