Action Items

1. Check with Sasha on steps for analyzing the random triggers in raw mode to check firmware (replay) Sasha said that there is no simple way of reading in the raw mode data taken in December and processing it using the replay mode for the firmware. We will need to check the hardware directly using data taken when the beam is off before the run starts.
2. Develop a plan for deciding on the fraction of empty target data to take (Rory and Ilya)

Preliminary Agenda
