Error bars for the estimated neutral magnesium escape rate and electron density at 3 Rp, in the G-scenario. The exobase is fixed at Rexo = 3Rp with a planetary wind velocity vpl − wind = 25 km s-1. A black star indicates the global best fit to the observations with Mg0 = 2.9 × 107 g s-1 and ne(3Rp) = 6.4 × 1010 cm-3 (χ2 = 802.4 for 1067 degrees of freedom).
