BEER-model M₂sini as a function of the BEER period. Large and small circles represent priority 1 and 2 targets, respectively. Green circles represent confirmations, while red circles represent FAs. Open circles represent candidates of spectral type later than G7. The horizontal dashed line marks M₂sini = 0.25 M_⊙, below which there are no confirmed targets. The vertical dashed line marks P = 1.4 days, to the right of which there are 18 FAs of spectral type later than G7, but only one confirmed binary (see Sect. 6.2).
