Corner plot showing the distribution of the population of BH pairs formed after the galaxy merger. The plot shows the primary mass m_BH, p, the secondary mass m_BH, s divided by the primary BH mass m_BH, s/m_BH, p, and the redshift of the galaxy merger z_merge^galaxy. The contours show the density of the points. Individual points outside the contours are also shown to visualize the extent of the distributions.
