furious-sections

Remaining figures to deal with:
3.2 - change in alpha in the small increments code
3.5 - dispersion at each altitude for 10keV protons
3.6 - integrated dispersion for 10keV protons
3.9 - product of scale height and collisions
3.11 - dispersion at each altitude for 10keV protons - Jupiter
3.12 - integrated dispersion for 10keV protons - Jupiter
3.13 - gyroradius with altitude - Jupiter
3.14 - product of scale height and collisions - Jupiter

Tables:
3.2 - integrated dispersion at 10keV for different pitch angles etc (Earth); mine plus lorentzens
3.3 - integrated dispersion at 10keV for different pitch angles etc (Jupiter): mine plus Earth ones

Ones that don't need cross-sections:
3.2 - change in alpha in the small increments code
3.13 - gyroradius with altitude - Jupiter

3.2 is in the middle of being calculated - ie loads of runs of the Earth model are off and going to produce the required results. All I need is 'stuff' from each one (total ionisation of the primary beam), which will show what happens as alpha changes. But they take a while to run - especially when there's so much else running on Rimmer...

So need to grab all cross-sections (again, this time with references, want to make this one airtight) and then recalculate dispersion accordingly. Also need to do this vip stuff. Later.

Collisions required:
Essential H/H+:
N
O2 - Rees H+/H Vanzyletal78 H Ruddetal H+ Yousifetal85 H/H+/H-/H2+/H3+ Porteretal76 H+ Ruddetal85 H+ (ionisation)
N2 - Rees H+/H Utterback and VanZyl N2/CO VanZyletal78 H Lunaetal H+ N+ Ruddetal H+ VanZyl83 H/H+ Yousifetal85 H/H+/H-/H2+/H3+ Porteretal76 H+ Ruddetal85 H+ (ionisation)
H - Copeland and Crothers H+ Gealy and VanZyl H/H+/H- Olson and Salop H+ ButlerDalgarno N+ Ajelloetal H- Butleretal O++ Ne++ Ruddetal85 H+ (ionisation)
H2 - Gealy and VanZyl H/H+/H- Tabata and Shiria H/H+/H2+/H3+/H2 VanZyletal80 H Hughesetal H+ (emissions) Ruddetal H+ VanZyletal89 H/H+ (emission) VanZyletal83 H (emission) Ruddetal85 H+ (ionisation)
He - VanZyletal80 H Ruddetal H+ VanZyletal86 H+ (emission) VanZyletal83 H (emission) Ruddetal85 H+ (ionisation)

Non-essential H/H+:
O
Ar - VanZyletal H Neumannetal H Ruddetal H+ VanZyle H+ (emission) Ruddetal85 H+ (ionisation)
C2H2
CH4 - Utterback and VanZyl N2/CO Ruddetal H+ Ruddetal85 H+ (ionisation)

I doubt I'll get the hydrocarbons, we shall see.

So those fully covered:
O2, N2, H, H2, He, Ar
Partially Covered:
CH4
Uncovered:
N, O, C2H2

in dire situations, can use shape factors to manufacture cross-sections for partially covered particles and N and O can have half the cross-section of their diatomic molecules. Hydrocarbons can be ignored for the time being.

Ok, now replacing, where possible, those that I can in the current system and putting in missing ones for (eg) Grodent's atmosphere. Doesn't really matter what I stick in for the Hydrocarbons as they're such a small proportion of the particles throughout the atmosphere... at least I hope in the dispersion region...

Why doesn't finder communicate with Safari and learn what "hide extension" means? Doesn't it know how much effort is involved in me ticking that box and then finding it hasn't done what is requested?

Have set off all alphas on C3 (not dealing with Keter on earth stuff). They are queued...

Dealt with H/H+ cross-sections for O, O2, N, N2, H, H2, Ar(H only) - He, Ar(H+), CH4, C2H2 will be dealt with tomorrow

Runs still queued
