This task started one month ago when I send the following e-mail to Andrew.

I found the effect (higher concentration at pitch angles of 0 and 90 than at 180 degrees)you mentioned in several graph through the year for the 3 of the four S/C: December (days 339, 344, 348, 353, 356), January (011, 013, 016, 018) June (168, 168,170,175,185) July
Cluster 3 showed a opposite behavior during those days.
You can see the plots HERE:

ii I was trying to confirm from where we I can get the Footpoint Magnetic Latitude and so plotted the Invariant Magnetic Latitude (JSOC), Magnetic Local Time(JSOC), Magnetic Latitude (AUX) and Magnetic Radius (AUX) on the spectrograms, but the data from JSOC do not seems to correspond to the foot point data we need.
The plots here:
http://www.mssl.ucl.ac.uk/missions/peace_ops/kjg/AAR/cmp1/index.php
Magnetic Latitude (JSOC) on HEEA@180
Magnetic Local Time(JSOC)on LEEA@180
Magnetic Latitude (AUX) on LEEA@0
Magnetic Radius (AUX) on LEEA@0
(187,189,192).

- Data from Dec. 2009 is not available yet.
- Currently Invariant Latitude (JSOC) and Spacecraft Local Magnetic time(JSOC) are available from March to April only.
- Should I prepare an evaluation of the assessment made in i?

they way I was looking for loss-cone distribution was only by comparing the concetration at 0 and 90 degrees to those at 180 degrees. I conclude that in not all th periods mentioned by our folks in Iowa the difference in concentration (0 and 90 > 180) was present. This probalbly means that other distribution are present during those periods.
Loss-Cone
| December 2008 | January2009 | June 2009 | July 2009 | December 2009 |
|---|---|---|---|---|
| 339 | 011 | 168 | 187 | 339 |
| 344 | 013 | 170 | 189 | 346 |
| 348 | 016 | 175 | 192 | |
| 353 | 018 | 185 | ||
| 356 | ||||
Note: days in bolds indicate those days mentioned by Christopher (from iowa) in his report May2009. however there are days mentioned in this report for which I didn't find the same effect(Janury 4th) or we dont have data (March 26).

I removed the files for which we dont have SPINPAD data (100 out of the 460 periods given, including decemebr 2009).
# find *.gif -size -17k -type f -exec mv '{}' empty/ \;
I added L shell values as Scalar to the graphs as well.
I would have like to look to the dates, such as Jan 11, but there is no MAgnetic data for that day on SDAAS and the magnetic data on the JP website seems to have some lag with the SSDAS magnetic data that we have in other dates.
Check March 04 here:
