TL;DR: In this paper, the OGLE-2019-BLG-0304 microlensing event was analyzed and the authors found that the residuals can be explained by the presence of either a planetary companion located close to the primary of the binary lens (3L1S model) or an additional close companion to the source (2L2S model).
