[PAC meeting]
- Today is sessions to correct inputs to reviewer and tomorrow there
is the closeout session in which the recommendation will be made.
- sPHENIX is requesting pp run as the highest priority.
-- CAD need more time to setup polarized pp, comparing to unpolarized pp
- BNL will have a budget to keep running RHIC until Jan 20.
-- It still depends on how long the ongoing government shutdown continues.
- If there will not be enough time for the pp run, OO run will be the
second option because it will be finished quickly.


[Etc]
- We will take zero field runs with different crossing angle this week.

[Yuko: Offline QA]
- Missing sectors are appeared not in the online monitor but in the
offline monitoring.
- The problem can be seen in both official and private DST productions.
- The evt file sizes are same for both good and problematic runs.
- Check rawhit contents and file size in the combined DST.
-- The problem should be in the event combiner.
-- The official event combiner is made by Chris.
- Jingyu checked recent runs and found 2 runs bad.
-- Offline monitor plots are archived so you can check more earlier runs.

20:20 → 20:40 Offline QA check

Speaker: Jaein Hwang (Korea University)

[Jaein: INTT offline QA check]
- In the official production only runs with long runtime are produced.
- INTT7 is shown by white mark which cannot be seen in the plot
- What is the large hit rate run? Probably it is a run at too
beginning of the fill.
- If 3 felix servers data missing, it will be classified as bad run in
the BCO QA.
- We should determine the criteria of the fraction of good channel as
good run for this year. 90% same as last year?
-- Check the 3 bad runs around ~90% to understand the cause before
deciding the criteria of the fraction of good channel for this year.
-- Maybe those runs has the same event combiner issue.
- Run24 pp and AuAu productions are done with the same criteria.
- Jaein will check the recent bad runs.
