Notes. Ranking according to the simulated mass-loss rates. Explanation of the columns: planetary name, X-ray luminosity (0.1242.48 keV), Lyα luminosity (Linsky et al. 2013), Lyα flux at Earth neglecting interstellar absorption; EUV lum. (100912 Å, Linsky et al. 2014), XUV flux at planetary distance; mass-loss rate from the simulations (1/4 × 4πR2ρv), total fractional mass loss in parts per thousand per Ga, fractional cumulative mass loss during first 100 Ma in parts per thousand, equivalent width of the Lyα absorption signal and in brackets the additional equivalent width caused by unbound hydrogen (optical transit depth is subtracted).
