            <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. 
                CPI/SWEA and LEP measurement are expected to be used in a complementary way. LEP is highly sensitive and is dedicated to 
                measure tenuous plasma of the magnetosphere. However, when GEOTAIL is in the interplanetary, LEP generally  scans only the 
                high energy (> 5 KeV) part of the ion distribution. This automated mode allows to assure long term preservation of the LEP 
                detectors. The LEP ion moments obtained in the inteerplanetary medium should be used only for qualitative purposes. 
                The ion moments in the interplanetary medium are provided by the CPI/SWEA instrument designed for 
                measuring the denser magnetosheath and solar wind plasma.
