Sasha showed <a
href="https://halldweb1.jlab.org/talks/2015/20150203"
class="external text" rel="nofollow">plots</a> of the
diffidence of mean times between specific counters one in
the front plane, one in the back. This simple study shows an
indication of time resolution for the TOF of about 100 ps
rms. He also showed a preliminary study of the difference in
timing between two separated counters in a single plane.

Beni has been looking at <a
href="https://halldweb1.jlab.org/wiki/index.php/First_look_at_TOF_data_from_Fall_2014"
title="First look at TOF data from Fall 2014">some basic
quantities</a> from the commissioning run with an eye
toward expanding our standard set of monitoring plots. There
are some mysteries. One of them is a strange set of
regularly spaced peaks in the total charge distribution.
<br>
<br>
Some of us (Brad, Aristeidis, Beni, Mark, Simon, Sasha) will
meet later in the week to plan some kind of structure for
capturing summary data from plots like these for long-term
monitoring of the detector.

Paul had started on a draft some time ago. He will try to
pick up that effort and hopes to have a draft in the Spring.
