    keyword=Optics Check: quick look on sieve in run with T6 trigger

    With T6 trigger, most event have tracks as well as passing good electron
    cuts. Here is 1M ev run 1769 with positron and central dp cuts cut.
    However, no software coincidence cut was applied. VZ strip is still more
    spreaded. And it appears there is no clear sieve holes. Could try more by
    varying cuts.
