Caption: Figure 1.
The projected oblateness parameters (top; to scale) and a comparison between spherical-planet and oblate-planet models for Kepler-51d (bottom). The models differ at ingress and egress (by ~200 ppm for f⊥ = 0.2 and θ⊥ = 45∘) from that of a spherical planet with the same cross-sectional area and orbital parameters.
