Dynamic REM maps (left column), variations of the inner eccentricity (middle column), and mutual inclination of the orbits (right column) for several cycles of oscillation of these elements in the (ΔΩ, i_c) plane. The top row is for the Newtonian gravitational interactions; the bottom row is for the GR perturbations included in the equations of motion. Black curves mark some levels of mutual inclination of the orbits. The points marked “1”, “2” and “3” are for the integrated initial conditions shown in Fig. A.3. See text for details.
