Detection efficiency for the LOPS2 + LOPN1 targets. (a) The distribution of detection efficiencies calculated for the targets, assuming the transit of an Earth analogue (P = 1 year, R = 1R_⊕) with cos i = 0. The colour of the bars encodes the mean magnitude of the stars within each bin. (b) The fraction of detectable planets (defined as planets with a detection efficiency >1/N_sample) for the thin disk, thick disk and halo populations, as a function of radius. The detection efficiencies are calculated for cos i = 0 and P = 100 days.
