Hi,
<div><br class="ContentPasted1">
</div>
<div class="ContentPasted1">Thanks Tim and all who contributed for putting the slides
</div>
<div class="ContentPasted1">together, it's a very nice status report highlighting physics

</div>
<div class="ContentPasted1">As far as I know Eugene has already presented the status of
</div>
<div class="ContentPasted1">Hall D during this week, but I think that he can use some of
</div>
<div class="ContentPasted1">these plots in his future reports. Please link these slides</div>

<div><br>
</div>
<div>Thank you for your comments.</div>
<div><br>
</div>
<div>Axel, I agree. </div>
<div><br>
</div>
<div>Or, I am not familiar with the details (Phoebe & Axel need to answer that), but at least we see the difference between AV4 and the other two in the region between 0.4 and 0.8 GeV.</div>
<div>This is similar for example to the Fig. 2 from Axel’s paper…again I do not know enough to discuss the differences in the shape (maybe smearing/bing migration plays a role?).<br>
<div><br>
</div>
<div>Best,</div>
<div>Tim</div>

</div>
<div>Thanks for preparing this. I agree with Axel’s comments and have a technical question:
<div><br>
</div>
<div>Fig. 2 should be the equivalent of the electros scattering (e,e’pp)/(e,e’p), right? If so, do we understand why <span style="">AV4’ shows the tensor deep (which I think it shouldn’t), and why the raise in A</span>V18 is relatively small? Also, how was
the k_rel cutoff handled? the GCF should not really be able to give you such low-Pm values, or at least we should not use them…</div>
<div><br>

<div>Thanks a lot to everyone who contributed to this!</div>

<div>Dear All,<br>
<br>
My apologies that this took longer than expected, but here is the final analysis status update that was requested by Eugene Chudakov. It was my understanding that this is for internal use, so I hope that the format is acceptable.<br>
<br>
Please check it if you can. Ideally if there will be no complaints or only minor corrections, I would love to see this go forward on Monday.<br>
<br>
Thank you and best regards,<br>
