    keyword=eP energy measurement: 1.198 GeV

    During 8:00 and 9:00 we did two runs of eP energy measurement (eP run 3107 and 3108).
    The energy measurement seems to be of very good quality (similar number of trigger in each arm, sharp coplanarity peak for both arms).
    The online analysis of the second run (109 events) gives a beam energy of 1.19786 GeV.
    First run (47 events) is not as reliable because the beam energy lock was accidentally turned off.
    The plot shows the measurement results for the two arms.
