Corner plot illustrating the posterior distribution for the binary fraction (f_bin) and period distribution exponent (π). The central (off-diagonal) panel displays the 2D joint posterior density, with contours indicating (2D) 1σ, 2σ, and 3σ confidence levels. The two marginal panels (diagonal) show the 1D distributions for f_bin and π, with vertical lines marking the 16%, 50%, and 84% quantiles.
