Feb 9, 2023 TPC meeting
Present: Yuri, Prahsanth, Alexei, Flemming, Tommy

--hardware
Westpole installed. #d sensor installed before and can be viewed so we 
can observe movement when filed is turned on, changed polarity etc.
Water leak in East laser box.  Alexei will investigate.

-	After insertion 2 bad FFEs identified. Likely due to squeezed cable. 
Need to ensure better pre-closure inspection for future years.

Software
  Tommy and Tonko identified one source of differences between online 
and offline clusters. Namely simulation of hardware asic that merged 
time sequences separated by just one empty timebin (below threshold) 
would be merged into one

Yuri reported that analysis of recent survey revealed that TPC is 
rotated relative to RFF.
Still needs to talk to survey group to understand coordinate systems.

Yuri reported (see meeting page) that the QA plots for pbar vs p vs pt 
for the period c (production nomenclature) ie. From after covid shutdown 
is different than before shutdown, Period “” and b .
