Number 
of target stars for which η ≥ ηmin, as a function of the number NT of telescopes observing them and the applied aperture model.

Notes.
We present above the case of an Earth-like planet with δp = 84 ppm, td = 13 h, ntr = 3 and SPRtot given by the simulated values presented in Fig. 17 (i.e. assuming no background correction). The values in this table were determined from our dataset of 50 000 target stars. The weighted values correspond to the effective 
, obtained by assuming uniform star distribution and a fractional field of view as given in Table 1.
