Sensitivities

Finally mastered 3d graphs for idl (that was a harsh half hour) and will be plotting out the survived results of sensitivities (ie all except 100k BSR 0.0 results).

There are three categories of graphs - BSR, SD and GS representing backscatter ratios, errors in atmosphere/cross-sections and Grid Size (atmospheric contraction/expansion induced changes) respectively.

Within each category, there are eight graphs, representing Peak ionisation rate, peak height measured by which altitude saw the maximum rate (monte carlo models have inherent random effects that can make this uncertain) peak rate as measured through an average of five or so levels rather than single levels (biased towards higher altitudes due to asymmetrical shape of the Bragg curve), FWHM, integrated ionisation, average energy expended per ion-electron pair created (assuming all energy goes into ion electron creation), peak as a fraction of integrated rate, peak rate position as a fraction of the distance from the lower half width to the higher half width. This gives twenty four sets of graphs in total.

Within each graph, the points are ordered by initial electron energy. There are ten electron energies, providing a total of 240 points to litter the appendix with. P.Multi may be used...

I can fit around eight graphs to each page, which gives me three pages of graphs... not the most exciting tract of the thing, but then again could be for not very exciting people... actually, maybe six pages, four graphs to a page, these are pretty big things once the annotations go on (as tested now).

Also need to decide which example graphs go in the main text to complete the figures in chapter four (I say complete, despite some figures not yet being in there and others mislabelled due to the removal of Uranus).

Now transferring some of the datasets:

BSR:
pr - done
ph1 - done
