Marginalised posterior distributions for M_BH, χ_BH, M_NS, log(Λ_NS), and joint posteriors for all pairs of these parameters. Black dashed lines in the plots on the diagonal represent the value corresponding to the 16th (left line), 50th (central line), and 84th (right line) percentiles. Red lines show the prior distributions. Black lines in the joint posterior plots represent one-, two- and three-sigma contours, while black dots show single samples in the region outside the three-sigma contour. Blue lines indicate the original values from which the mock data set have been produced.
