Binary detection probabilities of the SMASH+ survey projected on the mass ratio versus the orbital period (left), versus the semi-major axis (middle), and the companion mass versus the semi-major axis (right) planes. The colored background and solid equi-probability curves are based on the sample of stars that have been observed both by PIONIER and by NACO. The dashed equi-probability curves (and cyan labels) show the detectability when restricting the sample to ΔH ≤ 4 (i.e., the “cleaned” sample). From top to bottom: the full sample, luminosity classes I and II, and luminosity classes III to V.
