STAR QA Board

["Ting Lin" <tinglin@sdu.edu.cn>]

Hi all:

A brief minutes for today's meeting:
https://drupal.star.bnl.gov/STAR/comp/qa/pwg-qa/run-22-qa

For Run-22 offline QA:
>From Lanny Ray: 
  In run 23025052 RDO 11-2 was out, but not completely. The problem went away 
in run 025053 but returned in 025060, and remained fully masked out after 
that.
  In run 23027017 RDO 1-8 midpadrows displayed reduced hit number:
  In run 23024003 the dE/dx resolution was poor:
  In run 23022065 there are no TPC hits in the 4 files processed.
  In runs 23023022, 23027046 the BTOF, dEdx and MTD-TPC track matching plots 
are all empty. Usually this indicates the absence of a good start time for 
the collision. 
  Starting on Wed. (day 026) the run integrated signed DCA distributions were 
shifted negative < -0.8 cm.
     -> it maybe calibration issues, but calibration changes happen last week 
~Jan. 21, not likely to have big impact on this week.

>From pwg: 
 1. For run 23022065, Tof is out of this run, so 0 events with tof 
requirement.  
 2. JP2 and JP1 trigger ID changes (JP1: 890209 to 890229. JP2: 890210 to 
890230), related to the exclusion of the forward detectors from these. 
     -> Gene: For MuDst, see trigger ID for JP2 and JP1: root -l -b 
st_blah.MuDst.root, then: 
MuDst.Scan("MuEvent.mTriggerIdCollection.mL1TriggerId.mId[]")
 3. Continue to see Vz - VPD Vz = 5 cm in fast offline QA (same as last week, 
a mistake in last week’s email).
 4. There is shift observed in <DCA> and pion yields, at the same run 
23026056 seen by Bulkcorr group. Shift log says: "TPC sector 17 channel 3 
tripped, "clear trip" didn't work. We cleared it manually following the 
operations from the instruction, worked".
 5. Tong check the QA plots for "890210 trigger for runs 22351048 - 23019026" 
as asked by Raghav. Not all of the files are available, so it is not very 
meaningful to report/mark the problematic runs. 
 6. TPC calibration happened on Dec.22, Jan 21. So there maybe something 
changed after these date. 

For BES-II data QA:
  1. Dan is goring through the final 14.6GeV QA list. 
  2. Data production is going well, will have QA for the other dataset soon.
  3. Li-ke is writing a document about the QA.

Best,
Ting
