    • The range we adopt for (formula presented) is the 95% confidence range derived from the likelihood function based upon 3 events assuming Poisson statistics. However, the issue of uncertainties is far more complicated and the true 95% confidence range is probably larger

    • For example, the measured optical depth (formula presented) =(π/4E)(formula presented), where the sum i runs over events, t-|(formula presented) is the duration of event i, and (formula presented) is the “efficiency” of detecting an event of duration t-|(formula presented). The MACHO efficiency drops significantly for t-|(formula presented)<10da and (formula presented) could be larger than reported due to short-duration events. However, because of the null results of the EROS CCD search for short-duration events and the MACHO spike analysis it seems unlikely that this is the case
