Observability Predictor

Remarks

Mroz et al., 2020 : stellar companions is ruled out up to the projected distance of 8.0 au from the planet. The planet mass is ≈ 0.3 earth mass if the lens is in the Galactic disk (favored interpretation). If ther lens is in the Galactic bulge, the planet mass is ≈ 2 earth masses.
