Posterior distribution of four parameters used in our fitting procedure as applied to the Quadrantids meteors shower. Histograms in the outer plots show a distribution of statistically equivalent solutions. The plots inside the triangular structure show projections of these solutions onto two-dimensional planes of two selected parameters, where the color coding represents the density of solutions (increasing in density from blue to red). The graphs (left to right columns) show the distribution and correlation of the following parameters: (1) slope a; (2) offset b; (3) lower bound x₁; and (4) upper bound x₂.
