Uppersix panels: errors made on the orbital parameters as a function of the total path travelled by the planet, for each of the simulations in which a planet was correctly identified. In these panels, two cases, corresponding to a good fit (green dots)and a bad fit (red dots) of the orbit are highlighted. Two lower panels: corresponding orbits with the real orbit of the planet in black, and the orbit found by K-Stacker in green (good fit case), and red (bad fit case). For each orbit, the position of the planet in all ten images is also represented.
