<br>
We went over the <a

title="GlueX TOF Meeting, February 24, 2015">minutes</a>.
<br>
<ul>
<li> We discussed changing the pedestal level in the
FADCs to 100. We thought that that would be a good
idea just to be consistent with the rest of the
detectors.</li>
<li> Paul reminded us that we should be keeping track of
all significant actions involving the TOF in the TOF
electronic logbooks. He also re-raised the issue of
having log entries automatically emailed to a list,
perhaps <a class="moz-txt-link-abbreviated" href="mailto:halld-pid@jlab.org">halld-pid@jlab.org</a>. Mark volunteered to ask
about such a capability.</li>
</ul>
<br>
<span class="mw-headline" id="Calibration">Calibration</span><br>
<br>
Sean showed some plots showing time-of-flight between the
start counter and the TOF. Bands due to different
particles are not particularly visible. He emphasized the
need for calibration constants for timing, even
preliminary ones.
<br>
Sasha is continuing to work on the calibration with beam
data. He has a calibration based on cosmics that is nearly
ready for use. He will put it in the CCDB sometime in the
next two or three days.
<br>
For the beam data, he is having trouble with getting
constants for hits at the edges of the array.

<ul>
<li> We looked at the <a rel="nofollow" class="external
text"
href="https://halldweb.jlab.org/talks/2015/hot_check_out_tof.pdf">Hot
Check-Out list</a>. Sasha pointed out that we should
also be checking the discriminator scalers.</li>
<li> FSU will turn on detectors and start their
check-out procedure starting this afternoon. Mark will
inform Alexandre Deur of these plans.</li>
