Sorry Silvia for the misunderstanding, I'm on holidays the week of the collaboration meeting so I won't be able to give this talk. I've attached slides showing improvements for J/psi produced on the bound proton and J/psi produced on the bound neutron. For
whoever will give the talk, please feel free to take the plots you want from them and email any questions you have on the slides.<br>

we see an improvement of:</span>

<div class="PlainText">Dear all,<br>
next week at the CLAS meeting RGB will have a 15-minute slot to present<br>
"Pass2: First look at RG-B data". My understand is that Richard is<br>
available to give this talk (Richard, please correct me if I am wrong). It<br>
would be great if this talk could provide an overview on the impact of<br>
pass2 on all ongoing RGB analyses. Provided that Richard will be the<br>
speaker, could all RGB analyzers please provide him with one slide<br>
summarizing the impact of pass2 on their analyses? It can be focused on<br>
the overall increase of the yields, and/or resolutions, improved PID, etc.<br>
Thanks a lot and best regards,<br>
Silvia<br>
