First panel: detection limits versus noise for the full sample and no additional noise, averaged over all realizations. Color- and line-coding as in Fig. 13, panel f. The horizontal line is the 1 M_Earth detection limit level. Second panel: same, but for b_inst(t) of 0.5 m/s, for one realization. Third panel: same, but for b_inst(t) of 0.1 m/s, for one realization. Fourth panel: same, but for b_inst(t) of 1 m/s, for one realization. Fifth panel: same, but for b_inst(t) of 0.1 m/s added to b_gra(t) of 0.8 m/s, for one realization.
