Relation between the semi-major axis and Gaia RV amplitude (upper row), RUWE (middle row), and S/N(PMa; lower row) for previously known binaries in the young association stars (left column) and in the Hyades (right column). Filled blue circles are visual binaries; filled orange triangles are spectroscopic binaries; open squares are substellar companions. Horizontal short dashed horizontal lines are the detection limits for binaries; vertical black long dashed lines mark semi-major axis corresponding to periods of 34 months (for RUWE) and 24.75 yr (for S/N(PMa)) where maximum sensitivity are expected for these two techniques.
