All coalescence (top two rows) and all collision events (bottom two rows) from the eight N-body simulations. Plotted are product masses (m_coal or m_coll) versus distance to the cluster density centre r_dens. Columns from left to right show increasing rotation ω₀ = 0.0, 0.6, 1.2, 1.8. K models use a white background; NOK models are shaded light grey. Coalescence outcomes: MS (blue), CHeB (purple), ShHeB (orange), BH (black). Collision markers: BH-BH (black cross), MS-MS (cyan cross), BH-MS (violet cross). Counts in Table B.2.
