Quick note

Have transfered Grodent's atmospheres, total H2 ionisation rates and subsequent H3+ densities into a spreadsheet. The first bit needs conversion so the five species can be used by RIDE properly. The second bit is the direct comparison between my ionisation rates and his. The final bit compares our chemistry models. Might be interesting...

I was a little worried that leakage of the 20keV maxwellian beyond RIDE's upper limit would cause problems with electrons not creating enough ionisation at the bottom of the atmosphere. However, the atmosphere cuts off before that point anyway...
