Notes. “H/He” is the hydrogen/helium ratio used for the computation of the abundance profiles: values with a “*” were constrained by Lampón et al. (2020, 2021b, 2023), while the other ones were fixed to 98/2. “Extension” is the vertical extension, in planetary radius (Rp), of the atmosphere on which the abundance profiles were computed. We set it as the host star’s diameter to include all possibly absorbing layers at any transit phase. “R_lobe” is the Roche lobe of the planet, computed using PyAstronomy’s (Czesla et al. 2019) implementation of Eggleton’s formula (Eggleton 1983). “V_shift” is a constant Doppler shift applied to the modeled He triplet lines: it was fixed at a null value for nondetections, and was estimated using a simple Gaussian fit of the He absorption triplet in the data for detections and tentative detections by comparing the theoretical position of the strongest He triplet lines with the center of the best fitting Gaussian function. The error on V_shift are given for a 95% confidence interval. “Detection” indicates whether planetary helium is detected (Y), tentatively detected (T) or nondetected (N). “Stellar SED” is the name of the star from which the spectral energy distribution (SED) was used, taken from the MUSCLES database unless otherwise stated.
