Ellipsoid light curves compared to light curves generated via Pytmosph3R (i.e., spherical core, but atmospheric envelope). Rotation is taken into account for both methods. Left: light curves generated by Pytmosph3R (dashed line) compared to the spherical model (dotted line) and the ellipsoid model (solid line). Right: residuals of the spherical model (Sphere) versus Pytmosph3R (P3) and the ellipsoid model (Love).
