We went over the <a

title="GlueX Start Counter Meeting, December 12, 2014">minutes</a>.

<ul>

Eric gave an update.
<br>
<ul>
<li> Mahmoud Kamel is working on the timing calibration.
</li>
<li> Eric is working on the hit position correction to
timing.
</li>
<li> Eric, Simon, and Paul Mattione are looking at the
previously reported anomaly at 180 degrees in azimuth.
No charged-track-start-counter matches are found for
three counters in that region. The start counter hit
seems present, the charged track is pointing to it, but
the match is not registered.
</li>
<li> In the r-z view the intersection of tracks with the
start counter shows a large number of points that are
outside the physical counters, clearly a bug. Werner
thought that this should be addressed first.
</li>
</ul>

We went over the <a

title="TOF DAQ Tasks, January 22, 2015">list of tasks</a>
that Mark had put together for the TOF. Since these are
mostly generic they served as a useful list for the start
counter as well. We agreed that many of them should be
pursued and that the next step is to prioritize the list.
