Radius of the simulated planets as a function of the S/N of their transits. As in Fig. 5, green and black dots indicate the identified and missed planets, respectively. The vast majority of the discovered transits have S/N > 8 (red dashed line). Note that the x-scale in the left and right panels is different. See text for discussion about the transits with S/N ≥ 15 that should be easily detectable but were missed in our blind test.
