Trend of (S/N)_θ as a function of the total integration time T_T (the sum of the integration times of the measurements). The integration time for the first measurement is kept fixed to 10 ks. In this way, we compare results with the same total integration time (for the three-measurement scenario, the integration time T_T − T₁ is split equally into the two remaining measurements). The blue curve correspond to the case in which we measure three measurements with baselines 0.0, 0.6, and 0.8. The orange curve correspond to the case in which we measure two points with baselines 0.0 and 0.6. The green curve correspond to the case in which we measure two points with baselines 0.0 and 0.8.
