<Description>
The Solar Wind Analyzer (SWA) of the Comprehensive Plasma Instrumentation (CPI) on Geotail is a quadrispherical plasma analyzer
that measures three-dimensional fluxes of ions in the range 150-7,000 eV/Q.
Version 6 data processing replaced version 5 processing for data after March 10,
2006, when the CPI team started using 64 energy steps per spectrum instead of
the previously used 32 steps per spectrum. The change was made to ensure that
even for very cold flows, the spectrum would have a sufficient number of
significant points to derive moments. The change resulted in 96s spectra and
96s-resolution moments, vs. 48s previously.
