Notes:^§ This is the correct value, even if it is different from the value reported in the original paper (see Corrigendum).^† Our analysis favors the configuration where the stellar south pole is visible, and we use the corresponding stellar inclination derived by Sanchis-Ojeda & Winn (2011) from spot-crossing anomalies.
