Posterior samples for stable solutions characterized with |Δn| < 10⁻⁵ rad d⁻¹, and the semi-amplitude of the libration of the Laplace resonance argument |Δθ| < 60°. The starting solution that initiated nearby MCMC walkers in the emcee samplers is the periodic configuration in Tables 6 and 7 (Model 1). Uncertainties for the parameters are determined as the 16th and 86th percentiles of the samples around the median values.
