*a new .zip file from Erik, 18 September 2009–C2fields

Here is an explanation of the above files:

There are about 15 plots attached (if they fit), which are different visualizations of the CASCADES-2 DC E-field data over 3 different time periods of the flight. One of these is 300-310s, which I included to show the “noise level” in electric field data despun by a preliminary attitude solution (I think I can still reduce this noise), note that this is the region where the attitude solution does the worst. Most of this is due to error in the attitude solution and error in applying the attitude solution to despin the data.

The second is 586-590s which is a short period of really intense DC fields, but is short enough to fit lots of information on few plots. Looking at just the FWD and AFT data I think we observe vortices like what have been presented for the magnetosphere here (http://www.nature.com/nature/journal/v436/n7052/full/nature03931.html). But then when we difference the payloads we see even more structure, although the amplitude is smaller they are more frequent. I am going to bring this to Professor Seyler today to see what he thinks. It’ll be interesting to see magnetic fields here.

The third is the big field reversal at around 640s which Kristina seems really interested in. Here the 2d plots might be most illuminating. The noisy bubble in the 2-d hodogram of the differences is shifted ~20-30 mV/m north, ie if the field is 20mV/m stronger in the northern direction at the FWD payload and there is very little difference in the East direction. How far along is the camera data here? I think this data will be best interpreted at a velocity (V = EcrossB/B^2), which is something I am working on.
