TL;DR: In this article, the mass and distance measurements of two single-lens events from the 2017 Spitzer microlensing campaign were reported, and the ground-based observations yielded the detection of finite-source effects and the microlens parallaxes were derived from the joint analysis of groundbased observations and Spitzer observations.
