Green square points show the results of our SED fit to the KELT-11 catalog magnitudes (red circles). Using the Castelli-Kurucz model atmospheres (Castelli & Kurucz 2004), the Hipparcos parallax, and spectroscopic constraints on the effective temperature, surface gravity, and metallicity of KELT-11, we determine the stellar radius to approximately 10%.
