    keyword=timing comparison between LD2 x<1 and x>1

    As a sanity check, we compared the time for the neutron peak from the x>1 data to the x<1 data. This was after re-processing both sets of data with the same analysis code and correction factors.

    For x<1: - common stop formed by 980MeV/c protons in the L-HRS (tof=125ns) - NA time from 240MeV/c neutrons (tof=80ns) - NA.tr.tof found at 310ns

    For x>1: - common stop formed by relativistic electrons in the L-HRS (tof=90ns) - NA time from 300MeV/c neutrons (tof=65ns) - NA.tr.tof found at 285ns

    The difference in the common stop and the neutron tof leads to a shift in the measured NA.tr.tof, with x>1 expected to come 20ns earlier (in this common stop-measurement) than x<1, which is what we see.

    The measurements are consistent.
