Comparison of the basic parameters of the atmospheric outflow between models #0 and #1 (panels a-d) and models #0 and #2 (panels e–h). Specifically, the atmospheric mass-loss rate (panels a and e), the outflow density at R_roche (panels b and f), the outflow velocity at R_roche (panels c and g), and the total fraction of ions below R_roche (panels d and h) are compared. In each panel the x-axis corresponds to the value of the specific parameter predicted by model #0 and the y-axis corresponds to the same parameter predicted by model #1 (panels a–d) or model #2 (panels e–h). The different colours correspond to the different equilibrium temperatures and the different symbols correspond to the different planet types, as indicated in the legends in panels a and b. The black dash-dotted lines in each panel show the equality of the parameters predicted by the two models, and the additional grey lines show different ratios of the parameters P obtained from the different models in the form P_model#1/#2 = c × P_model#0, where the coefficient c is shown in the plots next to each grey line.
