Same stuff

Yep, marking. Halfway through the physicists.

Also discussed some stuff with Alan about a new version of TIROS. Looks like electrons fluxes etc can be generated through a set of calcs. I then have to come up with some sort of CSDA model seeded by my own that does the rest. Very possible. Have worked out enough for it to be better than TIROS, just a case of how much better.
