Results of our Monte Carlo simulations illustrating the sensitivity of our survey to spectroscopic binaries in the Hyades. The panels show our detection completeness as a function of orbital period, eccentricity (for PcircP ≤ 104 days), and mass ratio (P ≤ 104 days). Binaries with periods shorter than the circularization period Pcirc, taken here to be 5.9 days (see Section 11.2), are excluded from the calculation of our sensitivity as a function of eccentricity because their orbits have typically been made circular by tidal forces.
