Minutes

Attendees: David, Will M. (JLab), Will L. (CMU), Justin (MIT), Christine, George (Athens), Tegan, Ahmed, Andrei, Zisis (Regina)

1. Announcements: Justin was at Regina last week working with the group on BDT. An undergraduate student (Laura Teigrob) will be working with Tegan on the pedestals, a.o.
2. Action Items:
   1. Elton requested feedback on his two documents.
   2. No reply from Sean yet.
   3. Sean and Mark will work together on this; a) single FADC time slope constant, b) t-w corrections will follow a four-parameter equation, c) postpone TDC work on BCAL for now.
   4. Track matching: Justin reported that this is going well and provide some info, for example, for run 2400:
