Same as Fig. 2, but with more F_EUV values. Multiple dash-dotted lines of the same colour show the predictions of the energy-limited approximation for different F_EUV values, and the multiple sequences of circles of the same colours give the predictions of the hydrodynamic model for the corresponding F_EUV values (which coincide for the low-gravity planets). The considered EUV emission values are (from the bottom to the top line or sequence of each colour): 3.0, 375.5, and 3000 erg s cm⁻² for 300 K; 2.6, 89.1, and ~1.1 × 10⁴ erg s cm⁻² for 700 K; 16, 193.6, 543.3, and ~6.8 × 10⁴ ergs cm⁻² for 1100 K; 55.4, 669.6, 1878.6, and ~2.35 × 10⁵ erg s cm⁻² for 1500K; 175.2, 5937.3, and ~7.4 × 10⁵ erg s cm⁻² for 2000 K.
