Constraints on the SFDM profile for Ant B. The histograms along the diagonal represent the posterior distribution for each parameter: the virial mass, M₂₀₀ in M_⊙, the concentration parameter c₂₀₀, and the characteristic length scale of the repulsive SI R_TF in kpc. Their units are omitted for clarity. The vertical dashed lines indicate the median and 68% confidence interval (without arrows) and the 68% and 95% confidence limits (upper and lower arrows, respectively). The other panels represent the 2D posterior distributions of these parameters, with the contours corresponding to the 0.5σ, 1σ, 1.5σ, and 2σ confidence levels, where σ is the standard deviation of the 2D distribution.
