  "abstract": "We present high-angular-resolution imaging from the Hubble Space Telescope combined with adaptive optics imaging results from the Keck-II telescope to determine the mass of the OGLE-2012-BLG-0563L host star and planet to be M host = 0.801 ± 0.033 M ⊙ and M planet = 1.116 ± 0.087 M Jupiter , respectively, located at a distance of D L = 5.46 ± 0.56 kpc. There is a close–wide degeneracy in the light-curve models that indicates a star–planet projected separation of 1.50 ± 0.16 au for the close model and 8.41 ± 0.87 au for the wide model. We used the image-constrained modeling method to analyze the light-curve data with constraints from the high-angular-resolution image analysis. This revealed systematic errors in some of the ground-based light-curve photometry, which led to an estimate of the angular Einstein Radius, θ E , that was too large by a factor of ∼2. The host star mass is a factor of 2.4 larger than the value presented in the A. Fukui et al. discovery paper. Although most systematic photometry errors seen in ground-based microlensing light-curve photometry will not be repeated in data from the Roman Space Telescope’s Galactic Bulge Time Domain Survey, we argue that image-constrained modeling will be a valuable method for identifying possible systematic errors in Roman photometry.",
