Ratio of the mass-loss rates predicted for the test planets by interpol2021 (panels a and c) and interpol2024 (panels b and d) to the true values given by the hydrodynamic model, against Λ and Λ × K, respectively. The points are colour-coded according to the J_bord value. In panels (c) and (d), the red points have J_trans = 1, while the red points marked by a yellow plus are those with J_trans = 2. For reference, the two horizontal black lines in each panel lie at 0.5 and 2.
