1. Understanding the data - a first off-line look Sylvie Dagoret-Campagne EUSO-BALLOON Analysis Meeting, October 2-3 2014 1

2. Global look All packets over all runs, Try to understand the meaning data in the ROOT file, Try to understand the distribution of these data (expected or strange) Try to identify bugs or good data EUSO-BALLOON Analysis Meeting, October 2-3 2014 2

9. Trigger time uniformity ? S-Curve flat, probably OK, why peak on cputrigger Why is There this Bump in Cpu trigger ? Also smaller bump In acquisition Unit in Microsecond ? EUSO-BALLOON Analysis Meeting, October 2-3 2014 9

10. What is the exact definition of An event-life time, Can we understand why it is different For the various types of runs ? EUSO-BALLOON Analysis Meeting, October 2-3 2014 10
