[Halld-pid] Start Counter Meeting Minutes, June 14, 2018

[Mark Ito]

Folks,

We met only very briefly.

Sean reported that the discrepancy between the propagation time 
corrections obtained by him and by Mahmoud can be traced to the use of 
different plug-ins; Sean's uses all tracks for which there is a useful 
time, Mahmoud's uses only tracks matched to the TOF. These differences, 
mainly in the nose region are being resolved.

For now, for the paddle-to-paddle timing calibration, Sean is using only 
the barrel region of the start counter.
