OGLE-2015-BLG-1212的斯皮策微透镜视差观测决定性地打破了行星和双星解之间的简并性，当只考虑地基数据时，这种简并性有些模糊。只有8个可行的模型生存的初始设置的32个局部最小值的参数空间。这些模型清楚地表明，透镜是一个恒星双星系统，可能位于我们银河系的凸起，排除了行星的替代品。我们认为，几种类型的离散退化可以通过这种基于空间的视差观测打破。
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.
