<u><b>Hovhannes:</b></u> Done (pi0-mass) calibration for a good part of
the perpendicular runs; 72487-72820. Working on the 72400's as of now.
The reason for the break-up into sub-groups was from looking at the pi0
mass initially for the entire perpendicular set, the pi0 mass shifted
considerably to different values over time. This could possibly be due
to differences in HV settings/gain.<br>
<br>
<br>
<u><b>James/Jon:</b></u> Started looking at the deadtime for the
helicity scalers. This is to provide a cut for these scalers, which
will be for sub-sets of runs. Will prepare a table for this. <br>
<a class="moz-txt-link-freetext" href="https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Dead_Time#First_Look_at_Dead_Time:_8.2F11.2F2010">https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Dead_Time#First_Look_at_Dead_Time:_8.2F11.2F2010</a><br>
<br>
The Syncfilter is not going to be used anymore, because it is
incompatible with the helicity scalers. Most of the corrections are
already being done in the analyzer. <br>
<br>
Relating to this, Oscar suggested documenting the analyzer process with
a flow-chart, illustrating the input files as well. Jon volunteered to
work on this with help from Hovhannes.<br>
<br>
<br>
<u><b>Anusha:</b></u> Started comparing data to MC for NH3 targets.
The discrepancy for deltaP is from the radiative corrections not being
correct. Will get the correct ones soon. <br>

<br>
Calibrating beam position variable (Ty) from EPICS. Will make a table.
This would be necessary for the packing-fractions as well.<br>

<br>
Recalibrating HMS drift-chambers to account for the (ultra)low
efficiency periods.<br>
<br>
<br>
As always, please let me know if I missed anything or if I made any
mistakes.<br>
<br>
Next meeting will be Aug 18th at 15:30.<br>
