    keyword=Saturdays EP measurement

    EP Run 3139, using the trigger (EP detectors) S1 .and. S2 .and. C gives:

    Number of elastic evts 15 Number of elastic combi 23
    Coplanarity Cut (mm) 0 0 Coplanarity Average 0 mm
    Energy Cut (MeV) 0 0
    x beam position (mm) 0.0574142
    Measured Energy 2.26083 GeV +- 0.539074 MeV (stat) +- 0.48 MeV (sys)

    The quality is not very good, due to the loose trigger definition.
    (In fact, the automated code finds another beam energy, depending on
    the cuts chosen. but this result is unphysical, since it would require a
    unreasonable beam position)

    Runs including S1 in the trigger dont give any results in one arm.
