TL;DR: The analysis of OGLE-2016-BLG-0613 is presented in this article, where the lensing light curve appears to be that of a typical binary-lens event with two caustic spikes but with a discontinuous feature on the trough between the spikes.

TL;DR: In this paper, the authors present the analysis of the OGLE-2016-BLG-0733 microlensing event and find that the perturbation originates from the binarity of the source rather than the lens.

TL;DR: The analysis of the binary gravitational microlensing event MOA-2015-BLG-020 is presented in this article, where the light curve deviates significantly from the lensing model that is based on the rectilinear lens-source relative motion.
