Fig. 4

Difference in EUV flux at Earth values in the 90–360 Å wavelength range between those given by France et al. (2018) and those obtained by employing the scaling relation in France et al. (2018, Eqs. (4)–(6)) as well as the stellar parameters derived from the Gaia DR2 catalogue. The median difference is about 2% (red dashed line). Except for stars with low EUV fluxes (below 2 × 10−14 erg cm−2 s−1) the difference is within 10%.
