TL;DR: In this article, a test based on the microlensing event OGLE-2016-BLG-0168 created by a binary lens system consisting of almost equal mass M-dwarf stars was conducted to verify the micro-lens parallax and resolve degeneracies by using the space-based lightcurve even though the observations are fragmentary.
