days remaining/requested, which does not appear in the current document. I will revise that section based on the RGA discussion we had in one of our recent meetings and update the document accordingly.</span></p>

<div class="" style="word-wrap:break-word; line-break:after-white-space">Dear Latifa,
<div class=""><br class="">
</div>
<div class="">
<div class="">Thanks for putting the document together. I do not know how much it matters, but since we are using mC and not ABUs, I have questions about how these mC were calculated and what we will compare them with. </div>
<div class=""><br class="">
</div>
<div class="">According to our pass2 good ran list, for example, that we use for cross-sectionn measurements, the Falll 18 has only 68 mC (not 99 mC,) and Spring 19 is 46 mC (not 60 mC). </div>
<div class=""><br class="">
</div>
<div class="">Then, the MesonX’s approved beamline is not the largest. The TCS-J/psi experiment was approved for 100 days inbending and 20 days outbending for the full luminosity. Now, if we compare 126+99+60=285 mC with the 75 nA nominal current for 120 days
(778 mC), it will be only 37%. So, we still need 63% to finish.</div>
<div class=""><br class="">
</div>
<div class="">As I said, it may not matter, having 50% more running (60 PAC days) is fine with me. But I want to make sure we will have at least 60 morePAC days to run and that the numbers we quote are consistent with the approved time or the total luminosity
of experiments.</div>
</div>
<div class=""><br class="">
</div>
<div class="">Regards, stepan<br class="">
