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:
 1). Runs 23095006 – 23095038, 23096064: MTD was out of run 
     -> One of the MTD software is not running properly 
 2). Runs 23095006 – 23095052 (all day 95): BTOF was out of run Run 23095030 
has no TPC hits and could not be examined. 
     -> one of the THUB failed 
 3). Run 23096027 was very short; poor dE/dx resolution and low mean value. 
 4). Run 23097011 – no dE/dx, 1/b or MTD-TPC track matches
     ->  there is dE/dx cut used for MTD-TPC match, so if dE/dx is not there, 
then it will cause the problem.
 5). Runs 23096049 st_fwd, 23096063 st_physics and st_fwd, 23097012 st_fwd, 
and 23097073 st_fwd had an excessive numbers of missed MTD-TPC track matches.

>From PWG:
 1). Also confirm that TOF information is missing for runs between 23090032 
to 23091074, and also 23094049 to 23095052;
     -> TOF was taken out due to THUB current issues.
 2). vpdVz info not available for runs after 23091005, it is set to -999.0
     -> also due to THUB problem. 
 3). Continue to see double vz peak.
 4). TPC Vz - VPD Vz = 5cm
 5). See jump in BEMC tower multiplicities from 23089039 to 23089043 and also 
23094049 to 23095006
 6). See fluctuations in the Eemc tower multiplicities.

Best,
Ting
