Orbital frequency plotted against S/N for our resolvable binaries at a distance of 2 kpc and 5 years observation time. The different colors are explained in Fig. 2. Circles represent circular binaries. Triangles represent eccentric binaries that were not involved in any dynamical interactions after the formation of the DWD. Stars represent eccentric binaries that were involved in dynamical interactions after both components had evolved into WDs. The filled symbols show the complete set at a distance of 2 kpc and the unfilled stars show the resolvable eccentric binaries at 12 kpc. The blue points follow the same curve as the orange points but are hidden due to the large number of points.
