STAR QA Board

["Kaifeng Shen" <skfwyl@mail.ustc.edu.cn>]

Dear All,

    Please find the Mtd hits and matched check and |VpdVz - Vz| cuts check in 
this link: 
https://drupal.star.bnl.gov/STAR/system/files/20220311_pp_500GeV_Mtd_Vz_check.pdf
Any comments and suggestions are welcome.

Best regards,
Kaifeng

> 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.
