Chapter planning

Possible bits of chapter six:

Introduction
Fitting models to observations
-Initial idea of fitting
--Fitting 250eV protons, photons and electrons to single energy input
--fitting protons, photons and electrons to upper Grodent curve
--More advanced versions incl. elec. pa distributions, photon scattering
--Reasons for inclusion/exclusion - chemistry of above
-Makenzie's observations
--Grodent model fit and assumptions discussion
--Defficiencies and possibilities (pa, composition etc)
Results
Discussion

Back in chap. 5, inclusion of excited states should be done through parameterisation of the ionisation rate through the average electron energy.

There are two Rees models, both very similar, both based on the same concept as the photon model and therefore both very easy to use in chapter 5...

Have now acquired all quantities required for Rees1 and 2 asides from lambdas that need digitising. Tomorrow, will be calculating (having gotten over the cgs units problem...).

Have been going through all the comments in Chapter two and seeing a few amusing mistakes Alan has made (on top of those I have made - Spritzer is not an IR space telescope - Spitzer is, Spritzer is a drink...). We will have to battle it out over the biophysics though...

...all minor revisions done, but a few big ones to save for another day.

One comment was a request to expand on something - which is differences between ion production between electrons and protons. Hmmm. I will do two trios of examples in the ever exandable Makenzie chapter, which is about fitting particle outputs to observations. I will show the effects of 100eV protons, photons and electrons, then try to recreate a 10keV maxwellian proton ionisation profile with electrons and photons (seperately) to show the differences. This will be using the primary rather than secondary beam, but with also notes on 3D effects etc.

...continuing...

The never ending group of Grodent's seems to be ending. The alphas seem to have a similar idea, we shall see in both cases... one of the Grodent 1's actually finished, which is an unusual event, and looked pretty good, which is also unusual. Again, it is iterating back to the program's original configuration.

A few alphas finished today and finished correctly, meaning there's three remaining to finish and one that needs setting off again once the C3 is ready. It will be set off on a primary only attack, which shouldn't make any difference as there's no secondaries involved at this energy anyway...

Have also discussed chapter 2 with Alan, who's finally gone through it, which means I can hand over chapter three. Have added in Rego's reference to that chapter, still need the alphas, but he'll take it without that diagram.

Also done a bit more on Chapter five. Getting near to the end of what can be done on that one text-wise...

...and then got revenge for reviews by being given something from BAS top review. A few pages worth of notes on their interpretation of Tiros now colated...

Chapter five stuff

The new alpha seems to be even more laborious for the Grodents than expected, so may take a while longer than usual for them to finish... unless keter's gone down... again.

More stuff

Same beginning as ever - a clutch of Grodents, now iterating towards their final state.

Keter worryingly shaky, hope it doesn't go down soon, the first of the sensitivities are nearly ready to finish...

Question arrived from BAS, answer sent off.

Registration and abstract for the europlanet workshop (including people from BAS) now sent off.

A few more Uranus runs added for various reasons... to be revealed when and if they finish...

More plotting...

Something interesting to do - plot out the output of ionisation rates for RIDE and Tiros for Svalbard at the two solstices as well as electron spectra, at two am and two pm after week long runs for the various activity levels, as well as TEC for the two. Maybe add in somewhere like Milstone Hill too, just to show how the Tiros spectra break down.

A clutch of Grodents has been dealt with.

Weekend runs

Few more runs dun over the weekend. Saturn50 completed as expected, with no problems, also as expected, so another good reason to suspect the runs will be successful. Now just need to put Saturn50 back on for a full run.

Dun. Along with a clutch of Grodents, some phenomalogical work on Uranus and a few other bits and pieces.

Ok, present suggested system for Chapter Five:

Should put a bit about Richard Horne's stuff in there too, as it suggests further uses for the technique - must also qualify the use of this; normally CTIP is run during storm conditions (hence TIROS producing full oval coverage), but is limited by its pressure levels as to how high activity to go. For projects such as Alex's where lots of data is compared to CTIP, as the data is real data over a real timescale, it is mostly in the quiet time, so needs a quiet-time oval for a proper comparison.

Also done phenomalogical stuff for the final results chapter - after wondering how to fit the proton comparison to data in with the general theme of statistical patterns of electrons into a GCM, simple answer - high precision measuring of the characteristics of particle beams for later, better statistics and resultant models.

It makes sense to me...

Same things as ever. Alphas, Grodents, Chemistry and Sensitivities.

Minor problem identified in chemistry module. Now corrected and being tested.

Hmmm. Little, if any, effect... ok, on closer inspection, quite some effect, but not enough - need an ever longer run, which has now been set off on the c3. Lets see if that ever ends...

Also done some work on Chapter five, having tied the introduction into Chapter four and included the thread that will be the actual thesis of the thesis... I forgot how much was already in five! I'll be modelling again soon and producing pictures once I've dealt with a load of citations...

Bits and bobs

The validation test run gave the expected result - the code is fine, it really was just coincidence that all seven runs happened to suffer catastrophic errors due to mistakes with maintainance of the Keter mainframe! Idiots!

If it happens again...

At least all can be set off again. Now the task is to keep running these things until they finally agree to output something sensible... like results... Then again, I've been doing this for a year now...

A second program has given up its secrets - the chemistry module's apparent inability to do anything between a quick rough and ready run and an overlong run is down to one step where the log of the H2 density is taken and raised to an integer power of ten. Unfortunately, the natural logarithm had been taken, which effectively doubles what the log should've been... now that is corrected, I can fine tune it a little better. I hope... Then I'll be out of the situation where a small number of low lying high density regions fail to run whilst everything else goes fine...

All alpha runs dead as predicted. They're next for the change...

Chemistry is better, but not yet as it should be. I get results up and down the range, but a few are still a little too coarse. They will be sorted once again...

Alphas have all been recoded and set off once more. Chapter three's final bit may even get done! Assuming they ever leave this queue...

ok, some are off...

Couple of checks on Chapter five done

Chemistry module finished. H2 problem still there. Most confusing... will sort out another day

More of the same

Chapter 2:
7,364 -> 7,512

This was due to the last few references going in, when I set myself the challenge to find six of each of the three types of auroral models. Done. As is Chapter 2.

Also removed a huge block of text that was repeated...

Have removed the other block of text from chapter three that's now in the two intros.

Chapter 3:
1,122 -> 4,439

Have added descriptions (mostly complete) of all three major models. Minor models and validations to go... plus a little on proton dispersal.

Chapter 5:
3,986 -> 3,995

(adjusted a few things in titles)

Total:
19,224 -> 22,698

...this is going to take some cutting down at the end... still, at this rate I might be able to squeeze in one of the two projects I currently haven't done! Or maybe just finish that paper, or get on with experiments, or do one of the million other things I'm supposed to be doing

More thesis stuff

Chapter five is done, so far as something without any results can be, and something that hasn't yet been typeset in latex. But hey, its another 4000 words, which should just about half complete the chapter. Every section has been visited.

Next chapter... I suppose chapter four would be the easiest to deal with, even though the introduction cries out for attention... I have added a timeline to my thesis outline now.

So, where am I?

Intro:
70
Chapter 2:
1,836
Chapter 3:
1,122
Chapter 4:
1,193
Chapter 5:
3,986

(don't ask about the others...)

Total:
8,207

Maximum:
60,000

Fraction:
13.67%

Chapter five is on hold for results, part of chapter three also is, chapter six cannot be started yet (same with conclusions), Chapter four can probably be completed, same with the introduction and at least most of chapter two.

Lets see if that can be increased further today (having already increased Chapter five...):

Introduction:
from 70 -> 2,035

Total:
8,207 -> 10,172
16.95%

Thesis stuff

Did a few runs testing various pitch angle things

Rewrote the thesis outline to incorperate the new bits, then did a short form official outline for Jochen.

Tried to get hold of appropriate thesis latex templates, but David's legacy of shutting off access to all students who have left mean I have no access to such things...

Steve's off to get more cross-sections for me. Reliving his life as a chemist...

Tiros

6.4 KeV
1M+ (Hurray!)

9.4 KeV
10,000ok

14 KeV
1000ok

20.8 KeV
1000ok

30.5 KeV
10,000ok

Have retried 46eV now that I've fixed the excitation recording thing and, unsurprisingly, I guess, the bus error has vanished. This may also explain why the current longer things haven't had any errors yet...

Also had a chat with Richard Horne, plus student, plus Alan, about TIROS and his attempt on it. In addition, have started the chapter on this stuff and it is going well and quickly.

Ok, have run 46eV for a million electrons. It looks like the bus error really is dead (for now). So, I should be able to do the rest of the runs fine (ie using Keter).
