Results from numerical tests considering the orbits of the two companions as shown in Fig. 5. Here we consider an initial condition (IC 1) where the outer companion has been assigned an initial eccentricity of 0.90 (black dot in Fig. 5). All other parameters are as shown in Table 2. For the RADAU algorithm (top panels) we used an initial time step of 0.001 days. For the HYBRID algorithm (bottom panels) we used a constant time step of one day. For both algorithms we used an accuracy parameter of 10^-12. Orbital elements are sampled every day and are plotted until the ejection time of RZ Dra(AB)C at around 22 years.
