TL;DR: The ground-based (GB) microlensing is reaching its limits, underscoring the scientific necessity for a space-based survey as mentioned in this paper, and it is known that GB micro-lensing has found a break in the mass-ratio distribution at about a Neptune.

TL;DR: The analysis of OGLE-2017-BLG-0329 is presented in this paper, where the parallax model based on the ground-based data cannot be distinguished from a zero-dimensional model at 2$\sigma level, and the addition of the Spitzer data enables us to identify two classes of solutions, each composed of a pair of solutions according to the well-known ecliptic degeneracy.
