Notes. The first column lists the He abundance relative to hydrogen. The second and third columns give the stellar XUV (10–912 Å) and EUV (200–504 Å) flux at 1 AU and at the planetary orbit, respectively. The fourth and fifth columns list the stellar wind and planetary mass-loss rates, respectively, while the sixth and seventh columns give the peak and the FWHM of the metastable He I absorption (i.e. without the geometric absorption of the planetary disk). The absorption and FWHM values are the result of time averaging from −0.1 to +0.1 in planetary orbital phase.
