Dear CalCom,
we have just run a pass0, following FTOF calibrations, and produced
timelines for RGC Fall22. They can be found at this link:
https://clas12mon.jlab.org/rgc/Fall2022/pass0v1.04/tlsummary/

The corresponding recon files are at
/volatile/clas12/rg-c/productionNew/pass0/mon/v1.04/mon/recon/

I gave a quick look at the various subsystems. I noticed some out-of-specs
shifts for RF time (run ranges: 16912-16943, 17058-17071, 17252-17304).
The last two run ranges are shifted for FTOF time as well. ECAL looks
pretty good to me. DC residuals look pretty good aside for two
out-of-specs periods (16865-16869 and 16982-17028). HTCC has nphe
normfactor out of spec for all the runs with inverted solenoid polarity
(17185 onwards), and the timing is out of spec for all runs. CTOF and CND
have a 2-ns shift in the early part of the run (probably due to the early
"online" calibrations, that were done long before the 2-ns offset fix)
plus an overall need for timing calibrations.

Detector experts, please give a look to the timelines and let me and Li
(our chef, in cc) know your cooking needs.

Thank you very much for your support and best regards,
Silvia
