keyword=eP run (not very good)
I did two eP runs. The data are very noisy (acquisition rate about 10 time higher than expected). The eP hardware and trigger seem fine so the likely quandidate is a poor beam quality. Retune of the beam did not change the situation (second run).
Online analysis bring 5 good events, unfortunately all are in the bottom eP arm so there is no correction for beam angle and offset.
Maybe the offline analysis at Clermont will be able to extract events from the top arm to correct the bottom arm measurement. Even so, it is likely that this measurement is of poor quality.
