Francois,
<div><br>
</div>
<div>The RG-A fall 2018 run period that is being cooked is in the range from 5032 to 5419. The </div>
<div>run range from 4760 to 5031 will be investigated shortly. The calibrations were not finished</div>
<div>for this period because there were so many changes ongoing with regard to trigger, timing,</div>
<div>and voltage changes, that identifying only a few reference runs were not so simple. The plan</div>
<div>is to come back to this period after the outbending cooking gets underway.</div>
<div><br>
</div>
<div>As for what defines “good enough” for the calibration of each subsystem, this was guided</div>
<div>overall by the system specifications convoluted with what could be achieved at the current</div>
<div>time given the state of calibrations, reconstructions, and alignments. The calibration timelines</div>
<div>before the start of the inbending cooking were reviewed by the subsystem folks and by the</div>
<div>RG-A folks in detail in the days leading up to the start of pass-1 cooking.</div>
<div><br>
</div>
<div>For your specific questions on the DC, the calibration suite and calibration of reference run</div>
<div>was available only in the last few days before cooking began. The fluctuations in the residual </div>
<div>mean vs. run number are still being explored and a plan to reduce the variations is being </div>
<div>considered (e.g. correlating variations with atmospheric pressure). This is still a ways off in the </div>
<div>future, so we could not delay the start of pass-1 cooking for the first publication.</div>
<div><br>
</div>
<div>Regards,</div>
<div>Daniel</div>

<div dir="auto">Is there a subrange that was approved for cooking from this link, or was the full range from 4763 to 5655 approved? I see some fluctuations outside the range 4913 to 5540 for instance FD electron RF time. DC mean residuals also show
fluctuations comparable to their sigma</div>

<div>If you select RG-A, the latest timeline for RG-A 2018 is 2.2.8 (done just this weekend for the </div>

Dear All,<br>
<br>
the RGK pass0 timelines are ready ad available at<br>

please take a look at them to check for instabilities which may need <br>
