N2 - Spitzer microlensing parallax observations of OGLE-2015-BLG-1212
decisively break a degeneracy between planetary and binary solutions
that is somewhat ambiguous when only ground-based data are considered.
Only eight viable models survive out of an initial set of 32 local
minima in the parameter space. These models clearly indicate that the
lens is a stellar binary system possibly located within the bulge of our
Galaxy, ruling out the planetary alternative. We argue that several
types of discrete degeneracies can be broken via such space-based
parallax observations.
