Flux-ratio and semimajor axis marginal posteriors for an additional outer planet between planet b and the start of the outer debris disk. The black line gives the 84th percentile flux as a function of semimajor axis. No planet is detected, and our sensitivity is not strongly dependent on any of the orbital parameters within this range of semimajor axis.
