Notes. The sixth column gives the [Fe/O] coronal abundance (i.e. h: high; 1: low) considered for the computation of the stellar EUV flux incident on the planet in the 200–504 Å wavelength range and listed in column seven. Column 13 gives the effective absorption of the He I triplet. References: 1. Bonomo et al. (2017); 2. Triaud et al. (2015); 3. This work; 4. Fossati et al. (2022); 5. Gaia Collaboration (2021); 6.
