[Sbs] [EXTERNAL] Re: GEn-II analysis meeting tomorrow at 2:00 pm EST

[Hunter Presley]

Hi everyone,

We discussed a potential followup meeting scheduled for today to discuss
timing results which were being digested at the time of last Thursday's
meeting. An initial observation of default values for many of the hcal
timewalk parameters suggested something didn't go as planned with the
calibration. We are still in the process of diagnosing the issue with the
walk parameters but* think we may have figured out at least some of
the issue*. A small set of replays was submitted to check for improvement.
Over the weekend, quality checking scripts were developed to track the
calibration status. I've attached the initial quality check pdf produced by
Vimukthi which highlights the failure of the timewalk calibration for some
blocks (see block 25 for example). We have other replays running as well
aimed at comparing two separate implementations of the TOFcal procedure to
help locate any inconsistencies in one or the other which may contribute to
poor coincidence resolutions. As of this morning, we do not have a
definitive, successfully calibrated coincidence time, so I would suggest
not having the meeting today. Let's plan to meet Thursday at the normal
2:00pm time slot for another status update.
