Fraction of detectable planets for the whole sample and P1 subsample, as a function of planet radius and orbital period. Detectable planets are defined as planets with a detection efficiency ≥1/N_sample, assuming cos i = 0 for all planets. The white marker is located at P = 1 year, R = 1 R_⊕. (a) All LOPS2 + LOPN1 targets. (b) P1 sample (V ≤ 11 and random noise ≤50 ppm integrated over one hour).
