Notes. DA19: Díez Alonso et al. (2019); Don23: Donati et al. (2023); Fou23: Fouqué et al. (2023); Irw11: Irwin et al. (2011); Laf21: Lafarga et al. (2021); Med22: Medina et al. (2022); New16: Newton et al. (2016); New18: Newton et al. (2018); Pas23: Pass et al. (2023); Sha24: Shan et al. (2024). The uncertainties for the stellar rotation periods were taken from literature. When absent, we imposed an uncertainty of 10 % of the value of Prot, as justified in detail by Shan et al. (2024). Coordinates are listed as provided by Gaia Collaboration (2021).
