1. How to get the initial field values, such as vx,vy, eps,etc. The program
   needs some initial values to start the simulation. There might be some models
   that we can use to set the initial field values, such as msis model, satellite
   observation, etc. But are there other better methods for us to use to realize
   this and how are CTIM doing it.

2. In the model, CTIM uses shaun model to do get the ionized 
   molecular, such as O+, H+, etc,  properties. But in the simulation, some
   error message about the result of them is given by the program. You have told
   me that the program will try for five times, then it will set them to original
   values. If there better way to do this calculation and avoid meeting 
   such errors in the computation?

3. There are some parts in the program, which seems to be irregular. What I have            done is to have changed those parts that I think irregular and replaced them 
   with regular programming methods. Comparison between this result and former 
   result shows in large difference. But they do have differences in detail. 
   seems to be good too. 

4. In some part of the program, gwatts, cpcpd, levpi,etc, are used as the 
   parameters for
   certain functions. Could we find some way to derive these from MHD 
   simulation results? I think we can at least try to use MHD results to get 
   cpcpd and gwatts.

5. In MHD output, there are diffuse electron precipitation and discrete electron
   precipitation. We are not quite sure whether they can be used in place of 
   energy deposition in the original program of CTIM. Or what we should do, what
   other inputs are needed to finish this. 

6. A new version of CTIM has been made, which structurize the origianl version 
   of it and add the functions to interact between its result and MHD results.
   Since Tim has mentioned that he has some new modifications of the program, 
   so we should ask him what they have modified and if the new resutls are 
   better.

7. Ask Tim what we can do to help him achieve what he wants.

9. I discard many switches in the new program, which are not used and I think 
   to be very unlikely to be used in the tuture.

10. About Nmf2 and Nmf2h. I have used the way your proposed to calculate Nmf2 and
    Nmf2h. Should I ask them what they have done to get them?

11. In the original CTIM, simulation starts from noon and can last no longer 
    than a day. I changed that part and make sure that it can start at any time
    by setting different basetime and last any long period of time. I just want
    to make sure from Tim that there are no implicit constraints in the program
    to prevent me from doing so.

12. Report to Tim what we have done so far in this project. Should we do some
    preparation to provide 
    him the CTIM version that we have got?

13. One thing maybe I should mention is that, the result can only be reliable
    after certain time of simulation, because we need to make the initial 
    conditions and external input consistent.
 
14. For some parts of the program, such as shaun model, atmosphere tides, etc,  
    I did not try to change them because I do not know much about them. I just
    suppose they are right. But I would like to know what chages you have 
    done on them so that I can make relevent changes.
   
15. For values such as hite, rn, etc, should I use the same set of values, or 
    chage them according to different settings. If so, what should I do it.

16. Test cases and data to compare. Community events.(CEDAR events. ISEP 
    events.

17. When does CTIM becomes independent of initial conditions?

18. Whether CTIM always starts from the same set of initial condition, or 
    they are dependent on the time.

19. Do you really start from noon?

20. What direction do you think is the positive direction of electric field.

21. Is there possibility to use global electric field, which can be 
    provided by jimmy's simulation?

23. How to make 20 plots:
   1) Run CTIM to get the new CTIM and MHD data. Be sure to change the 
      head of tucan.f to exclude the part of transforming old CTIM data!
      This run can get sm_data_new*** for both CTIM_MHD and MHD.
   2) Run CTIM_om to get the old CTIM data. This run can get 
      **.dat. 
   3) Copy the old ***.dat's to the directory of CTIM. Change the head
      of the CTIM-MHD tucan.f file to process the old data files and
      produce sm_data_old*.dat. 
   5) Run 'Combine' to combine the new and old data into 'b017' files.
   4) Copy the b017* files into directory /home2/ylwang/ctim/Show 
      directory. Run mak20 to get the corresponding ps files. Note: It
      seems that there is something wrong with the mak20 file. So if it
      does not work well, you can just process one file after another.
   5) That's all!
