      Review of minutes from the previous meeting

We looked at the minutes from August 16th 
<https://halldweb.jlab.org/wiki/index.php/GlueX_TOF_Meeting,_August_16,_2016#Minutes>. 
Since the last meeting, Beni has produced updated plots of efficiency 
versus run number with error bars.


      Run Plan

Beni and Brad have been working on new code to get an estimate of good 
starting values of the high voltage based on the HV scan done at the 
beginning of the Spring 2016 run. It plots the pulse amplitudes versus 
end-to-end time differences. The idea is to find, for each tube, the 
lowest voltage that will put the pulses above discriminator threshold 
for a minimum ionizing hit at the far end. These results will have to be 
adjusted for long-term gain reduction suffered during the run. The 
exercise will be repeated with beam data once that is available.
