Notes. The columns list the following quantities: 1) and 2) stellar name and alternative identifier, 3) spectral type, 4) mass, 5) radius, 6) rotation period at equator, 7) equatorial projected rotational velocity, 8) inclination, 9) X-ray-to-bolometric luminosity ratio (Wright et al. 2011), and 10) CaII H&K index (Noyes et al. 1984; Boro Saikia et al. 2018). Columns 4) and 5) are from Cristofari et al. (2023), and columns 7) and 8) are from Morin et al. (2008), Hébrard et al. (2016), and Cristofari et al. (2023). Columns 9) and 10) are from Wright et al. (2011), Stelzer et al. (2013) and Boro Saikia et al. (2018), respectively. The dagger (†) indicates that the parameter was estimated in this work.
