Plots of the statistical distribution of the simulated radial velocity slope using the model developed in Chauvin et al. (2012), for three different masses: 1.2 M_Jup (red line), 9 M_Jup (green line) and 24 M_Jup (blue line) and semi-major axis in the range 8.5 − 8.5 AU (left) and 11.5 − 12.5 AU (right). The vertical grey/black bar shows the measured slope value, which is also the 3σ upper limit of the slope.
