...continuing...
Microdice has been cleaned up a bit with declination angles removed (explicitly, they had actually been taken half out anyway, or at least stood down in the code). The beta correction had been done a long time ago, so no problems on that front.
Bit of research has brought out the screened rutherford cross-section for backscatter as the best way of doing the scattering. Protons are very pointed in their scattering ie they head forwards and backwards with little going off to the side compared to electrons, which are more pointed than photons. In addition, whilst photons backscatter isotropically in angular redistributing interactions, electrons are biased forward and protons are extremely forward biased.
The calculation for proton backscatter now puts the total RBSR cross-section over the total cross-section, but corrects to isotropic if the energy falls enough to allow this. Of course, DICE uses a variety of heavy particles to go bang (and the formula can cope with the lot of them) as well as electrons, which will use the BSR currently in RIDE.
This means adding in proper cross-sections. This will be long and painful.
So the cleanup is pretty much complete, asides from completing BSR calculations for DICE. Then its onto slicing down the numbers of altitude levels... Small increments will then happilly work everything out again... I was going to say if small increments was in DICE, but it is.
