Inferred system parameters from TAP MCMC analysis of Kepler light curves as compared to the work by [43]. For Kepler 4–7, the difference between TAP and KB10 fits hold no statistical significance. The larger differences seen in Kepler 8 analyses are likely a result of the enhanced noise in the Kepler 8 dataset and the inclusion of RV measurements by KB10.
^aParameterization of agreement: the significance of the difference between TAP and KB10 parameters. Fractional difference = (TAP-KB10)𝜎²_TAP+𝜎²_KB10.
