But these results need correcting<br />
• Recently EROS (Glicenstein 2004) found that<br />
event LMC-23 bumped again after 7 years =><br />
variable star, not lensing.<br />
• LMC-23 contributed 8% of optical depth (and<br />
halo fraction) (6% for set B), so all our optical<br />
depths and halo fractions should be reduced at<br />
least 8%.<br />
• => best f = 18.5%, and tau=1.1 10^-7 (<strong>Griest</strong> &<br />
Thomas), or f=16%, tau=1 10^-7 (Bennett)<br />
• More worrying: are there more events like this?
