Evolution of the mono-energetic Pedersen conductance computed with TransPlanet (green and orange curves), a Monte Carlo simulation (red curve) and the analytical expression from Hiraki & Tao (2008) (blue curve) giving the ion production rate. The green and red curves are computed with the same ionization cross sections of H₂, which are the cross sections used in this study, and the blue and orange curves are computed with the ionization cross sections from Hiraki & Tao (2008).
