'''Daily Meeting [https://bluejeans.com/454783784 BlueJeans]'''



=== Production Run List - Slug 136 - IHWP IN - Flip-RIGHT - Production ===
Start this slug at ~10:04am, February 16
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6439_000 Run 6439]
** Aq slightly larger in minirun 0, detector width is also large. USR has ~11% residual correlation with AqDS
** ~10 ppm larger detector slope
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6440_000 Run 6440]
** LQ1 tripped, applied event_cut at the end of the run
** Detector width is still large
** BCM asym noisy in the first half
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6441_000 Run 6441]
** LQ1 tripped, applied event_cut at the end of the run
** Very short run
** Detector width is still large
** Large residual correlation of detector (USR) with AqUS and AqDS
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6443_000 Run 6443]
** Detector width is still large
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6444_000 Run 6444]
** Detector width is still large
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6445_000 Run 6445]
** '''Large Aq for minirun 4''' (4.88+/-2.30)
** Detector width is still large
* NeedCut - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6446_000 Run 6446]
** Energy BPM wires saturated
** Detector width is still large
* NeedCut - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6447_000 Run 6447]
** Energy BPMs saturated many times. FFB ON/OFF to investigate this issue
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6448_000 Run 6448]
** Some beam excursion in the beginning of the run
* NeedCut - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6449_000 Run 6449]
** ~ 1mm of beam excursion at the end. Quite large Aq in 0th and 2nd minirun
* NeedCut - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6451_000 Run 6451]
** ~ 1mm beam excursion in the beginning
* NeedCut - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6452_000 Run 6452]
** ~0.8mm of beam excursion at the end. 4ec again sees this huge. bpm12X also has ~0.8mm-1mm of excursion
** Due to the excursion detector yield has changed (increased in USR and decrease in USL). SAMMs also see this.
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6455_000 Run 6455]
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6456_000 Run 6456]
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6457_000 Run 6457]
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6458_000 Run 6458]
** Aq little bit noisy at the end part of the run
* NeedCut - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6459_000 Run 6459]
** Some intermittent energy excursions ~1mm

=== Production Run List - Slug 137 - IHWP OUT - Flip-RIGHT - Production ===
Start this slug at ~04:02am, February 17
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6460_000 Run 6460]
** An outlier in MAIN det asym
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6461_000 Run 6461]
** Some beam excursions but looks good
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6462_000 Run 6462]
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6463_000 Run 6463]
** Large Aq in 0th minirun (~4.58+/-1.88 ppm)
** Don't see any obvious reason for this
* Good - [https://prex.jlab.org/analysis/crex/index.php?run=summary/all/run6464_000 Run 6464]

== Non-Production Runs and Bad Runs ==
run6442 --> Junk
run6450 --> Junk (Carbon 1%, MCC trying to fix energy drift)
run6453 --> Junk (Lots of GAIN search failure)
run6454 --> Junk (Carbon 1%, MCC trying to fix FFB)
