<div dir="ltr">Hi everyone,<div><br><div>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<b> think we may have figured out at least some of the issue</b>. 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.</div></div><div><br></div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Wed, Apr 30, 2025 at 8:16 PM Arun Tadepalli via Sbs <<a href="mailto:sbs@jlab.org">sbs@jlab.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
