Geotail magnetic field data updated for 2004-2006 because starting in 2004 we found the time intervals between successive "3-sec" points was typically slightly less than 3 sec. This affected our determination of 15 sec averages.
Geotail plasma parameters updated for 2006 because the instrument team modified its algorithms to reflect a doubling of spectral resolution in distribution functions, and halving of time resolution, in early 2006, relative to prior data processing.
