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.

TL;DR: In this paper, the authors conducted a proper motion survey in the V and I bands in order to determine the cool white dwarf contribution to the Galactic dark matter, using the 250 2 for which they possess three epochs, and applying selection criteria designed to isolate halo-type objects.
