    keyword=good event decline, parity trigger problem?

    We notice that starting with run 2902 (BEFORE the last NMR run),
    the number of events in singles has declined relative to parity. We have
    been running for 70,000 parity events and getting about 1.57 M, 1.51 M (L/R)
    and later getting only 1.29 M, 1.23 M (L/R). The number of good events
    in the phys replay had declined accordingly. We find nothing in the analysis
    that looks unusual, and since both arms have declined the same, we conclude
    that the parity trigger must be taking more events/beam current.
    A. Deur will come in 30 minutes for evening shift, we will ask him for ideas
    on the problem.
