Detection probability as a function of the observation time for a single planet in circular orbit with period 17.5 hr around a solar-type star, for test , at P_FA= 1%. The orbital inclination is set to 90 degrees. The different panels show the influence of the planet’s mass (a), the orbital period (with the corresponding orbital frequency on (black) or off (gray) -Fourier grid) (b), the time sampling step (c) and the size of the training data set (i.e., the number of available noise times series) (d). In each panel, the black curve indicates the P_DET obtained for a configuration in which the planet has a mass of 0.5 M_⊕, a circular orbit and L = 20 HD time series are available for periodogram standardization. The point where P_DET reaches 80% for this configuration is indicated by the blue disks. In each panel, the legends indicate the parameters under study. The dashed lines represent the planet’s detectability in the case where the noise is white (instead of colored) but with the same standard deviation as the colored convection noise (σ = 49 cm s⁻¹).
