Sasha gave the report.
<br>
<ul>
<li> He is almost done with putting calibration constants
into the TOF hit factory.
</li>
<li> He has been putting constants into a CCDB SQLite
file. He need to transfer them to the MySQL database at
JLab.
</li>
<li> He has numbers for time-walk corrections, time
offsets, and speed of light. There are still global
offsets in time difference, one per plane (top vs.
bottom or north vs. south), to be determined. These can
be addressed by looking comparing time differences with
the position of charged particles hitting the TOF.
</li>
<li> Sasha is working on the sim-recon trunk. He will have
to move the commissioning branch to pick up the
run-by-run calibrations for resolving the 6-fold global
time ambiguity of the CAEN TDCs.
</li>
</ul>

We had a discussion of many items on <a
href="https://halldweb1.jlab.org/wiki/index.php/TOF_DAQ_Tasks,_January_22,_2015"
title="TOF DAQ Tasks, January 22, 2015">the list</a>. For
next time we hope to have basic calibrations in place,
formulate a conceptual design for a gain balancing
procedure, and have preliminary numbers for time resolution
of the detector.
