OGLE-2016-BLG-1093Lb: A Sub-Jupiter-mass Spitzer Planet Located in
  Galactic Bulge
  OGLE-2016-BLG-1093 is a planetary microlensing event that is part of the
statistical $Spitzer$ microlens parallax sample. The precise measurement of the
microlens parallax effect for this event, combined with the measurement of
finite source effects, leads to a direct measurement of the lens masses and
system distance: $M_{\rm host} = 0.38$--$0.57\, M_{\odot}$, $m_p =
0.59$--$0.87\, M_{\rm Jup}$, and the system is located at the Galactic bulge
($D_L \sim 8.1$ kpc). Because this was a high-magnification event, we are also
able to empirically show that the "cheap-space parallax" concept Gould & Yee
(2012) produces well-constrained (and consistent) results for $|\pi_{\rm E}|$.
This demonstrates that this concept can be extended to many two-body lenses.
Finally, we briefly explore systematics in the $Spitzer$ light curve in this
event and show that their potential impact is strongly mitigated by the
color-constraint.
