[Clas12_calcom] [EXTERNAL] Re: new timelines for RGC-summer22

[L Smith]

Dear Silvia,

The missing 2.2 ECAL plots are due to missing re-assigned e- trigger bits during RG-C for that energy.

I used calibration and pass0 runs to evaluate calibration needs for energy and timing.  

Energy (SF and pizero invariant mass) looks fine for 2.2 GeV and timing required two table entries which are now in CCDB (https://logbooks.jlab.org/entry/4236819 <https://logbooks.jlab.org/entry/4236819>).

ECOU timing has outliers in sector 4 starting at 16308 but this seems to be a tail skewing the fit. I’ll work some more on it but this shouldn’t stall pass1 review.  

Best Regards,
Cole
