<li> Beni completed Hot Check-Out for the Start Counter.</li>
<li> We are still thinking about a Start Counter
Maintenance Program.</li>
</ul>
<h3><span class="mw-headline"
id="Calibration_and_Efficiency">Calibration and
Efficiency</span></h3>
<p>Mahmoud had no new news to report. He noted that he and
Sean Dobbs and agreed that there was no need for a new
set of calibrations from Fall 2018 data; the start
counter performance has been pretty stable.

<h3><span class="mw-headline"

Counter time resolution CCDB table fix</span></h3>
<p>Simon reported on <a rel="nofollow" class="external
text"
href="https://github.com/JeffersonLab/halld_recon/pull/96">this
recent pull request</a>. The new CCDB table that
contains resolution function information was not being
referenced correctly in the code. Now it is.
</p>
<p>Simon also told us that there remains a bug in
halld_recon causing crashes in reconstruction jobs, with
high-level detector timing. These have shown up in
recent monitoring launches.
</p>
<h3><span class="mw-headline"
id="SiPM_dark_rate_measurement">SiPM dark rate
measurement</span></h3>
<p>Mahmoud mentioned Beni Zihlmann's log entry on the SiPM
dark rate run mentioned at the last meeting. Data has
been taken and the analysis is likely in progress.
