Hello

We are having more backgrounds compare to run15. For example,
some of FCS triggers, like hadron triggers, see x2~x4 more trigger
rate than we should at early fill. See bottom plot of

https://online.star.bnl.gov/fcs2024/trg/rate/fcsHad2.rate.png

where ZDC coincidence & MC rate normalized trigger rate (should
be around 1 / green line) shows 2~4 more rate early fill.

Do you have any plots from FST/STGC QAs to show this background issue? 
Something like # of hits or occupancy plots vs run? Do you see the
fill structue in any of your QA plots?
