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 23064046 decreased number of hits in Sector 9, anode/RDO 6 for both 
st_fwd and st_physics; but hit density is not affected. -> Gain for the RDO 
is less. RDO-6 for this run is masked out for future offline analysis.
  2). Run 23066075: bad BTOW pedestals Gene discussed this with Navagyan 
Ghimire who reviewed the pedestal upload history. From the QA shift report: 
Pedestals for BEMC were reset for runs 23066073, 23066074, 23066075, and 
23066076. Those runs will likely not be usable for analyses. -> This may have 
impact in BEMC vertex finding, need to check in the offline analysis if they 
are good to use.
  3). Runs 23066068 and 23069015 MTD – TPC track matching was anomalous with 
a very high peak at 0. 

>From PWG groups:
Cold QCD:
 1). For day 061 (Idx [0-14]), the FCS chain options were included and that 
lead to problems with the MuDst files. The FCS chain options were out for the 
other days. 
 2). Still seeing very low nTCan and nTZero。  
 3). Slightly higher EemcTwrMult

LF:
 1). Some picoDst root files (23066068) in RCF show a problem: no keys 
recovered, file has been made a Zombie. Can not gain access to these files.
 -> 5 jobs complete without errors, but others have errors, Gene will follow 
this up.

BulkCorr
  1). Continue to see double TPC Vz peak.
  2). TPC Vz - VPD Vz = 5cm

HF:
  1). A laser run 23066046 has large deviation in VpdVz, Vz-VpdVz, 
VpdHitEast/West, primary Vertex (x,y,z), primary track eta, mtdDeltaZ
  2). Do not have electron candidates in 23066004~23066082 (33 runs, many 
short runs);
  3). Need to check MTD Hits plot, MTD matched hits plots for Runs 23066068 
and 23069015 MTD issues seen by Lanny.

JetCorr
  1). 23066032 only has 2 files in the offline production. 
   -> Some issues about iTPC bad channels fail the production.

Best,
Ting
