Prediction in the evolution of the logarithm of the Bayes factor when targeting with KOBEsim a period P_peak (each chart), but the signal is induced by a planet at P_planet (see legend for colors). All the cases induce a signal of semi-amplitude K = 6 m s⁻¹. The solid lines are the cases in which KOBEsim is pursuing the correct period (P_peak = P_planet). The black line corresponds to the active-star case. After the first ten observations it is assumed that the signal is turned off (K = 0).
