TL;DR: In this paper, the authors reported the discovery of the microlensing planet OGLE-2018-BLG-0740Lb. The planet was detected with a very strong signal of δ(n 2 ) 2, but the interpretation of the signal suffers from two types of degeneracies: close/wide degeneracy and ambiguity between two solutions, in which one solution requires to incorporate finite-source effects, while the other solution is consistent with a point-source interpretation.
