Gaia color–magnitude diagram of members of NGC-752 from E. L. Hunt & S. Reffert (2023). Circles indicate catalog stars, red “X”s are stars we excluded because of evidence of binarity or concerns about reliability (e.g., high RUWE, inconsistent periods between TESS sectors, high CMD position), and blue squares are stars with rotation periods used in this analysis. Approximate T_eff is shown on the top for reference.
