keyword=coinc time plot kin 155Original corrected time spectrum indicated real:accidental ratio on order of
1:4. Plot below shows how this can be cleaned up using cuts. First plot
is corrected time straight from espace with no cuts (upper left); next plot
(upper right) includes proton ID cut using beta vs. geom. mean of S1 in
hadron arm; next plot (lower left) shows inclusion of cut on vertex difference
(e.reactz-h.reactz) of less than 3 cm (!) Can likely do better offline but
online resolution in this vertex difference does not allow tighter cut.
