Corner plot showing the PPD on σ_los, v_sys and f for a mock catalog of 20 stars in two cases. Single-epoch observations (red: not correcting for binaries; black: applying a statistical correction for undetected binaries), and three-epoch observations (blue: by excluding stars with velocity variability >3× ∆v_los; green: as the blue, but also including a statistical correction for remaining undetected binaries). The contours indicate the 1 and 2σ ranges. The underlying values used to generate the mock are indicated with orange lines.
