Posterior distributions of fit parameters of HD22532. Each panel contains the two-dimensional histograms of the 1 200 000 samples (after removal of the burn-in, the first 25% of the chains). Contours are drawn to improve the visualization of the 1σ and 2σ confidence interval levels. The upper panels of the corner plot show the probability density distributions of each orbital parameter of the final MCMC sample. The vertical dashed lines mark the 16th, 50th, and 84th percentiles of the overall MCMC samples, delimiting the 1σ confidence interval.
