    • The Poisson probability that a mean of 1.1 gives rise to 8 or more events is 2.0 ×10-5, but this estimate of significance does not consider the statistical error on the background, while the procedure with binomial probability does.

    • The binomial probabilities for continuum plus B overline{B} backgrounds fluctuating up to the numbers of observed signal events are larger than the probabilities for continuum background alone by at most a factor of 4 for the K*0γ mode, and a factor of 1.4 for the K*-γ modes.
