2DTF maps obtained for different geometries of a binary system with disc-like BLRs. The insets present the orbital phase of the binary system corresponding to the map. The direction of motion of the binary SMBH is anticlockwise. Panels a–c: coplanar circular case obtained using the parameters from Paper I (see their Fig. 2a); panels d–f: same as panels a–c, but the inclination of the smaller SMBH orbit is 30°; panels g–i: coplanar elliptical binary system with e = 0.5, Ω₁ = Ω₂ = 0°, ω₁ = 0, and ω₂ = 180°, and orbital parameters of the clouds of e_c1 = e_c2 = 0.5, Ω_c1 = Ω_c2 = 100°, ω_c1 = 0°, and ω_c2 = 180°; and panels j–l: same orbital parameters for the binary system as in panels g–i, but the orbital parameters of the clouds are e_c1 = e_c2 = 0.5, Ω_c1 = Ω_c2 =100°, and ω_c1 = 110°, ω_c2 = 290°.
