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:
  1. Run 23042061 TPC Sec. 5 RDO 6 was only partially filled with hits. QA 
issue # 18095. -> happen several times during Run22. Some minor issues with 
RDO, started a new run will fix the problem. 
  2. In run 23043075 st_fwd data stream, the dE/dx mean is much too high and 
the ionization energy band resolution is very poor. The st_physics data dE/dx 
for this same run are normal.
  3. In runs 230045045 the dEdx, TOF and MTD-track matching QA plots are 
empty. In the past this indicated loss of VPD start time.
  4. In runs 23043051 and 044033 there is an enhancement in the number of 
BTOW clusters from f = -2 to -1 rad. -> 043051 is a very short run.
  5. Run 043051 only has 1 file processed so far, while 044033 lists ZDC/EPD 
AND rates as “-1/-1”. -> A very short run, no samples in the database, will 
get “-1/-1”. Again, if it is a very short run, SL should mark it as bad.

>From Cold QCD:
  1. 10% BEMC multiplicity gradually decreases from 23042001 to 23045006. 
Also from Run 23045006 To 23045007, there is a jump. It looks like there are 
several “BTOW configuration failed for crate Id 1. • Had to powercycle iTPC 
RDO S4:3.” error continues to happen in some of the subsequent runs around 
that time.
  2. Run 23042056 To 23042057, there is a jump 20% increase of EEMC tower Et. 
Did not see anything in the run log that might explain what happened.

>From BulkCorr & HF:
  1. Continue to see strange multi-peak Vz distributions; do not know what 
the problem is. We start to see this since last week from st_physics branch.
  2. Also continue to see TPC Vz - VPD Vz = 5cm

For BES-II 14.6GeV QA:
  1. Li-Ke and Ahsik updated the run-by-run QA results with duplicated 14.6 
GeV data.
  2. 100 consistent bad runs, Ashik find 5 extra bad runs,Li-Ke find 10.
  3. Total 1470 runs, 369(25.1% of total runs) injection runs excluded, 115 
(7.8%) bad runs flagged
  4. Total 651M events, 42M(6.5%) injection runs, 44M(6.7%) bad runs

Best,
Ting
