Notes. (1) Feinstein et al. (2022); (2) Suárez Mascareño et al. (2022); (3) Høg et al. (2000); (4) Gaia Collaboration (2021); (5) Skrutskie et al. (2006); (6) Nguyen et al. (2012); (7) this work; (8) Maggio et al. (2022); (*) Suárez Mascareño et al. (2022) report a slightly smaller value of R* = 1.29 ± 0.07. As the two values are consistent with each other within 1 σ, we adopted the value of Feinstein et al. (2022) for consistency with their fitting of TESS light curves.
