OGLE-2018-BLG-0799Lb: a q 2.7 × 10<SUP>-3</SUP> planet with Spitzer parallax
We report the discovery and analysis of a planet in the microlensing event OGLE-2018-BLG-0799. The planetary signal was observed by several ground-based telescopes, and the planet-host mass ratio is q = (2.65 ± 0.16) × 10 -3. The ground-based observations yield a constraint on the angular Einstein radius θ E, and the microlensing parallax vector $
