TL;DR: The OGLE-2016-BLG-1190Lb is the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two epochs of high-resolution imaging of the combined source-lens baseline object.

TL;DR: The analysis of OGLE-2016-BLG-0613 is presented in this article, where the lensing light curve appears to be that of a typical binary-lens event with two caustic spikes but with a discontinuous feature on the trough between the spikes.
