Run-by-run QA for Run20
In addition to the PWG QA by Ben and Takafumi, here is some QA of specific observables for the eTOF:
The calibration was done using runs 20345015 to 20346003 and is stable since then with the occasional global time shift when eTOF misses the reset signal from bTOF or in some cases after an eTOF DAQ restart.
These have not been taken into account for some runs in this QA, but they can be corrected for the final production, e.g. via a hybrid start time approach between eTOF and bTOF
There are some issues with clock jumps on the Get4 level that need further investigation and special treatment.
The matching ratios are averaged over all runs in one day. Before day 353 in some of the runs eTOF was not included, so the ratio is lower. I'll redo those plot with the runs without eTOF excluded.
From run 20352037 on, there is a special triggerId for all events with eTOF included and only those events are sampled in the ratio plots.
