The self-starting Radau IIA integrator is at least comparable with the best of other integrators in speed and accuracy, and it is often superior, particularly at high accuracies. Here, integration of the normalized two-body problem from t0 = 0 to t = 86400 for an eccentricity of e = 0.1 is implemented.
