Comparison of FriendFinder results obtained using the Gaia DR3 RV (left) and the M. B. Lund et al. (2017) RV (right) for KELT-20. Plotted are the differences between predicted (Vr,pred) and observed (Vr,obs) RVs as a function of the absolute Gaia magnitude. Blue circles mark stars with RUWE <1.25. The M. B. Lund et al. (2017) RV yields a closer alignment with the overdensity, supporting its adoption in this analysis.
