Distributions of suppression factors and semimajor axis cuts from 10⁶ chains of an MCMC analysis to model the observed close binary suppression seen in systems with TESS planet candidates. Solid lines indicate the median value of each distribution (a_cut = 46 au and S_bin = 0.24), and dashed lines mark the 68% confidence interval. The two parameters are correlated, such that less suppression is required if the semimajor axis cutoff is larger, and vice versa. A blue circle marks the values of the best-fit model from the Kepler sample of Kraus et al. (2016).
