<div>Hi Sean, <br>
MO signal that we have is at ~499MHz (and it will be prescaled
before arriving to TDCs to much lower frequency), <br>
but the beam bunches themselves should now arrive to Hall D and
the tagger hall at ~249MHz frequency. <br><span class="HOEnZb"><font color="#888888">

<span>Review of minutes from April 15</span><br>
<br>
We went over the <a href="https://halldweb.jlab.org/wiki/index.php/GlueX_Offline_Meeting,_April_15,_2015#Minutes" title="GlueX Offline Meeting, April
15, 2015" target="_blank">
minutes from last time</a>. <br>
<br>
David gave us an update on his Geant4
implementation. He as put in the FDC and
FCAL and can reconstruct tracks in the
FDC with resolution comparable with
those found with HDGeant. He ran into an
issue with multi-threading; a bug report
has been submitted to the Geant4
Collaboration. <br>
<br>
<span>Offline Monitoring</span><br>
<br>
Kei reported he has run over most of the
files collected in the last week of
data-taking. The volume of data is
small, it only takes a few hours to run
over everything.
<br>
<br>
We then discussed doing a final run over
the Fall data so that people can use the
data to prepare for the collaboration
meeting. There is a change to get the
setting of the F1-TDC parameters from
the CCDB that Justin checked in
yesterday. There are also new TOF timing
constants that we are not taking
advantage of yet. In addition Lubomir
also has new FDC alignment numbers. For
all of these reasons a re-run seems
desirable but time is running short to
have the data available in time to be
useful. We agreed on a launch time
target at the end of the day on Friday.
<br>
<br>
There was a bit of discussion of what
data we have from the current run. Most
of it is in run 2931, which is contained
in just over 100 files and has about 75
million events. Data were taken in mode
7 with an FCAL-BCAL trigger.

<br>
<span>Spring 2015 Commissioning
Simulations</span><br>
<br>
Sean described the <a href="https://halldweb.jlab.org/wiki/index.php/Spring_2015_Commissioning_Simulations" title="Spring 2015 Commissioning
Simulations" target="_blank">
conditions</a> he is proposing and
solicited feedback. The software has
been tagged but not released. Paul noted
that the nominal position of the
coherent peak is 3.4 GeV. The gxproj4
account will be used to run the jobs.
<br>
<br>
On a side note, Mark has put in a
request to the Computer Center for a <a href="https://halldweb.jlab.org/wiki/index.php/GlueX-related_shared_accounts_on_the_JLab_CUE" title="GlueX-related shared accounts
