NGC 6240 initial configuration for our triple SMBH physical model. The colour spheres represent the stellar bulges S1, S2, and N with central SMBHs (circles with dash edges) and stellar bulge B without a central black hole. SMBH initial velocities are noted V_{S1, S2, N}. Initial separation for pair S1+S2 is noted as ΔR₁₂ and for pair S+N is noted as ΔR₂₃. The initial velocities are calculated in the assumption of initial orbital eccentricity e₀ = 0.5 for both binary pairs. The radii of the spheres are scaled according to their bulge sizes (cutting the radius of the Plummer spheres).
