TL;DR: The OGLE-1999-BUL-32 microlensing event was observed by the MACHO-99-BLG-22 team as mentioned in this paper, which has a parallax effect that allows one to determine the Einstein radius projected on to the observer plane as r E 29.1 au.

TL;DR: In this article, the authors fit the data for the binary lens microlensing event MACHO 98-SMC-1 from five different micro-lensing collaborations and find two distinct solutions characterized by binary separation d and mass ratio q: (d,q) = (0.54,0.50) and q = (3.65, 0.36), where d is in units of the Einstein radius.
Journal ArticleDOI
Microlensing Optical Depth toward the Galactic Bulge Using Bright Sources from OGLE-II

TL;DR: In this article, a measurement of the microlensing optical depth toward the Galactic bulge based on 4 years of the OGLE-II survey is presented, where only bright sources in the extended red clump giant (RCG) region of the color-magnitude diagram are considered.
