Sample of transit timing variations caused by a hypothetical P2 = 10   000 day-period m3 = 0.005   M   (≈5   MJ) mass third companion for CoRoT-9b at four different initial mutual inclinations (im = 0°, 40°, 46°, 90°, from up to down), and three different initial outer eccentricities (e2 = 0, 0.3, 0.7, from left to right). The dynamical (relative) arguments of periastrons are set to g1 = 69°, g2 = 90°. The curves show the sum of the geometrical LITE, and the dynamical terms obtained both from numeric integrations, and analytic calculations up to sixth order in e1. The pure LITE contributions are also plotted separately. Note that the vertical scale of the individual columns (i.e. different e2-s) are different.
