Hi Daria,
The trigger hists look normal.
ESUM threshold moved from 250 to 300 MeV as expected.
The electron trigger rate dropped by 10% but
the electron trigger purity dropped by 4%.
Regards,
Valery

Many thanks, Yordanka!

Valery, Rafo, I'm particularly flagging this one up for you -- it's the run we took with trigger v13, with the PCAL+ECAL energy sum set to 300 MeV threshold.

Thanks,
Daria

Dear All,

If it will be of help to anyone, I have processed 1M events of this high
priority run and monitoring plots can be found at:
https://logbooks.jlab.org/entry/3750407

Please, note that in these histograms, the muon-trigger purity is based
on +- and -+ charged-particles pairs only. ++ and -- pairs are not
counted. This decreases the purity by about 30% from ~75% to ~52%.

For a larger statistics, we are waiting for 257 files from this run to
be processed on the farms (job is currently active). I will let you know
when the full stat monitoring becomes available.

Best regards, Yordanka
