Present:

  * *FIU: * Mahmoud Kamel
  * *JLab: * Thomas Britton, Mark Ito (chair), Simon Taylor


      Review minutes from the meeting on January 24

We went over the minutes 
<https://halldweb.jlab.org/wiki/index.php/GlueX_Start_Counter_Meeting,_January_24,_2019#Minutes>. 


  * Beni completed Hot Check-Out for the Start Counter.
  * We are still thinking about a Start Counter Maintenance Program.


      Calibration and Efficiency

Mahmoud had no new news to report. He noted that he and Sean Dobbs and 
agreed that there was no need for a new set of calibrations from Fall 
2018 data; the start counter performance has been pretty stable.


      Start Counter time resolution CCDB table fix

Simon reported on this recent pull request 
<https://github.com/JeffersonLab/halld_recon/pull/96>. The new CCDB 
table that contains resolution function information was not being 
referenced correctly in the code. Now it is.

Simon also told us that there remains a bug in halld_recon causing 
crashes in reconstruction jobs, with high-level detector timing. These 
have shown up in recent monitoring launches.


      SiPM dark rate measurement

Mahmoud mentioned Beni Zihlmann's log entry on the SiPM dark rate run 
mentioned at the last meeting. Data has been taken and the analysis is 
likely in progress.
