Notes. The significance of an RV mass measurement is here defined as med(k)/σ(k), where med(k) is the median of the RV semi-amplitude posterior estimate and σ(k) its standard deviation, while the RV measurement precision is σ(k)/med(k). The number of 1 h long exposures used in the simulations is marked by N_obs, and low, high, rocky, water, and puffy refer to different planet mass scenarios leading to RV semiamplitudes of 1.9, 8.3, 5.4, 2.8, and 3.3 m s⁻¹, respectively. For SPIRou, we consider the lower and upper precision limits of 6 and 11 m s⁻¹ per exposure separately. The estimates should be considered somewhat optimistic since they consider only photon noise and do not include the RV signals due to stellar granulation and variability.
