Notes. The secondary component’s potential, radius and log g are not noted as these parameters have no signature in the light curve and radial velocity data. The fractional radii quoted are the radii relative to the semi-major axis. For the mass and radius of the primary component, see Table 1. The limb darkening coefficients (x1 and y1) are for the square root limb darkening law and were taken from the phoebe limb darkening tables (Prša et al. 2011). For the beaming case we assumed 100% of the flux comes from the primary component.
