Distribution of particles final ejection direction by the IMBH binary on the timescale T = 2–8 Myr for NGC205 with 1:4 mass ratio. The color code is time in the left panel and the number of particles in each bin in the right panel. Black (left) and red (right) crosses on the plots’ top are the IMBH binary angular momentum direction. The asymmetry in positive and negative θ directions is at the level ≈40%. Particles generally are ejected in the direction of the IMBH binary orbital plane for a chosen time interval.
