      Review of minutes from the last meeting

We went over the minutes from the July 1st meeting 
<https://halldweb.jlab.org/wiki/index.php/GlueX_TOF_Meeting,_July_1,_2020#Minutes>. 


  * Sasha has finished testing all of the 23 new PMTs. Recall that there
    is one problematic tube.
  * Both of the issues on energy agreement between Monte Carlo and data
    on the GitHub repositories (one in halld_sim, one in hdgeant4) have
    been closed.


      Run Readiness

Beni showed plots of ADC pedestals, pulse amplitudes, pulse integrals, 
and time spectra for all TOF channels from a recent cosmic run. The 
pedestals had already been adjusted by hand to the four problem channels 
near the nominal 100 counts. There is a clear channel in a board (16 
channels) visible both in the pulse integral and timing plots. Sascha 
Somov plans to replace that ADC today.

the paper.
