Result of grid search and local optimization procedure used for finding plausible system architectures. We explored period ratios between the hot Jupiter and unseen perturber ranging from PHJ/P2 = 0.02–10 and optimized a TTVFast model to fit the observed TTVs, TDVs, and RV data. No unique solution for the unseen perturber could be found, with the most likely families of solutions from our search clustered around the 2:1 and 3:2 period commensurabilities with the hot Jupiter.
