Dispersion in parameters from the error-accommodation method. Each graph shows intrasystem dispersion distribution in the main sample acquired by running 10⁵ random uniform simulations within the error intervals. From left to right the distributions are obtained for radii, masses, densities of adjacent planets in systems with at least two planets and period ratios in systems with at least three planets. The blue dash-dotted and black dashed lines indicate mean and median values, respectively. The solid blue line indicates the best-fitted probability density function (PDF) of the normal distribution. The y-axis shows the probability density (the probability per unit on the x-axis).
