Membership diagnostics among the sources in our survey. We employ cuts on parallax (p) and proper motion (μ_α, μ_δ) to remove interlopers; these boundaries are indicated by solid black lines. RV is not used to remove noncluster members as it may be biased by the presence of a binary. Many of the sources identified as interlopers by their discrepant parallax and/or proper motion values also fall outside the pre-main-sequence region in the ﹩\mathrm{log}\,g﹩ versus T_eff diagram, enclosed by the solid lines, which confirms their status as interlopers.
