 === Detection efficiency for Gaia ===
 Over 5 years of operation of Gaia, there should be around 3000 microlensing events occurring in the Bulge. Assuming mean time-scale of 30 days and mean detection efficiency for events before the peak of 30%, it means about a 1000 events towards the Bulge should be detected by Gaia.
 Over entire sky there is something like 750 events expected to happen during the mission. If the mean time-scale is about 15 days, the mean efficiency is about 20%, thus there should be additional 150 events detected all over the sky before they reach the peak brightness.
