1) Data production
- Run17 pp 510 GeV st_physics MuDst->PicoDst conversion: confirmed latest BEMC calibration parameters used; initial QA feedback provided; production resumed
- Run18 Isobar 200 GeV st_hf, DAQ production: waiting for QA feedback
- Run18 Isobar 200 GeV st_mtd, st_upc, DAQ production: need to provide chain options
Conclusions: conveners will follow up on st_hf QA and chain options for st_mtd and st_upc

2) A few small, high-priority datasets to be duplicated on distributed disk
- Proposed datasets: Run18 3 GeV FXT, Run19 19.6 GeV and 14.6 GeV, Run19+20 FXT various energies (?)
Conclusions: will ask to duplicate Run18 3 GeV FXT, Run19 19.6 GeV and 14.6 GeV for now. If more datasets (small, high priority) need to be duplicated, will do so later on. We will also need to monitor if such a duplication improves the situation or not. 

3) List of ongoing analyses for each dataset and PAs
- Need to provide such a list to DOE, who might use it to determine computing support for STAR in the future
- For the measurements listed, we need to publish them
Conclusions: 
- This list is needed for both currently available datasets, and future ones to be collected in 2022-2025
- Will focus on big-picture datasets, such as Run22 p+p, Isobar, BES-II data, etc, instead of each individual data sample. 
Management will provide a list of big-picture datasets
- Will list institution names, rather than individual PAs
- Management will provide guidance on how such a list looks like. Each PWG will then collect information and send the list to management. 

4) Embedding requests
- Are the following still needed?
  • 20180201: He3 in AuAu 39 GeV, reproduction
  • 20185201, rh0, f0, f2, omega, eta in Run17 AuAu 54 GeV
  • 20203002, Ks/Lambda/AntiLambda in Run14 AuAu200 GeV HFT
  • 20203003, pentaquark in Run14 AuAu 200 GeV HFT
  • 20193803, neutral and charged k* embedding for Run14 AuAu200
  • 20210401, charged particle in Run17 AuAu54 GeV
  • 20210402, charged particle in Run18 AuAu27 GeV
  • 20210403, charged particle in Run10 AuAu39 GeV
Conclusions: LFSUPC and FCV PWGs will follow up on this

5) QM needs
  • Embedding
    • JetCorr: #20214101, #20184801 (good to have)
  • Real Data
    • LFSUPC: Run19 Au+Au 200 GeV
Conclusions: all the abstracts from LFSUPC have needed embedding samples ready. Recent requests from LFSUPC are good to have, but not absolutely needed. The embedding team will produce the requests that are needed for QM with a higher priority before going through "good-to-have" requests.
 
AOB: it was brought up that dE/dx values have visible dependence on pT, rapidity and time for 19.6 GeV and 14.6 GeV BES-II data. If using PID for these data sets, extra care is needed to account for the dependence properly

NOTES

2) eTOF development
- eTOF software coordinator is working on adding flags for each eTOF counter to PicoDst to indicate whether the counter is good for analysis. Such information is only available for 2020+ though.
- For people who want to use eTOF in 2019 (19.6 GeV, 14.6 GeV), they should discuss with eTOF group about how to study acceptance fluctuation and its impact on efficiency 

3) Disk space needs for distributed disk in the future
- Are PicoDst and Jet tree sufficient for Cold QCD group in 2022 and 2024?

Conclusions: the combination of PicoDst and jet tree are sufficient for current analyses in Cold QCD PWG. Conveners will confirm this at the PWG meeting next week.

4) Common bad run list, pileup rejection and centrality for BES-II
- Will use the tools developed for Isobar blind analysis
- We already have volunteers who started working on 19.6 GeV data
- Discussions and approval will mainly happen in QA board and centrality focus meetings
- A bad run list will be determined for centrality determination. How about analysis specific bad runs? Shall we collect inputs from each PWG and pass them onto the volunteers?

Conclusions: 
- A dedicated mailing list is created for centrality work (https://lists.bnl.gov/mailman/listinfo/star-centrality-l)
- Conveners will collect lists of variables for QA in the next couple of weeks. The final combined list will be discussed and passed onto people who are working on identifying bad runs. The goal is to create common bad run lists for different sub-systems, such as TPC. EPD, TOF, etc. This does not preclude people from checking more variables and possibly identifying more bad runs in the future. Should that happens, the findings need to be communicated to the collaboration. This needs to be done quickly as BES-II data are being produced.
- It was also brought up that centrality distributions should be checked if additional bad runs, on top of what's used for centrality determination, are rejected.

5) Need to identify one more volunteer for TPC related work (LIST)

Conclusions: volunteers are welcome
