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.
