Orbits of the Kepler-11 system with initial parameters from Lis2011 model (circular model, see Table 2). The planet marker size is scaled with the mass of the planet. Top-right: “Sky Plane”, Kepler-11 system as seen from the Kepler satellite; we plotted only one orbit near a transit for each planet. Each circle is the position of a planet at a given integration time step. Bottom-right: projection of the system as seen face on. The big markers are the initial points of the integration. Bottom-left: RV model from the simulation.
