The effect of a non-zero planetary mass on the predicted times of transit of KIC 4862625. Keeping the best-fit parameters of the circumbinary system constant, an increasingly more massive planet introduces significant deviations relative to the best solutions for a massless planet. While it is unlikely that the mass of the planet is larger than a few M _J, it adds a significant complication to the best-fit models, again indicating the non-unique nature of the solutions.
