    keyword=Absolute scint efficiency

    I modified the algorithm a little bit so that it tries to
    compute the absolute efficiency, using minimal 'cleanup'
    cuts. This works fairly well on the Left spectrometer
    because T4 uses the gas Cerenkov, but T2's on the Right
    spectrometer are very dirty (the 'or' of S1,S2), so this
    presumably makes the efficiency artificially low. The
    main thing to look for is a big hole. More accurate
    results --> offline.
