Description
This file contains numerical moments computed from measurements of the 
Los Alamos Magnetospheric Plasma Analyzer (MPA) [Bame et al., 
Rev. Sci. Inst., in press 1993]. 
The moments are presented in s/c coordinates: the z-axis is aligned with 
the spin axis, which points radially toward the center of the Earth; 
the x-axis is in the plane containing the spacecraft spin axis and the spin 
axis of the Earth, with +X generally northward; and the y-axis points 
generally eastward. Polar angles are measured relative to the spin axis 
(+Z), and azimuthal angles are measured around the z-axis, with zero along 
the +X direction. The moments are computed for three 'species': 
lop (low-ener. ions, ~1eV/e-~130eV/e); hip (hi-ener. ions, ~130eV/e-~45keV/e);
 alle (electrons, ~30eV - ~45keV ). The electron measurements are obtained 
21.5 secs after the ion measurements. Epoch is the measurement time 
appropriate for the ions. The moments are computed after the fluxes are 
corrected for background and s/c potential. Algorithms for these corrections
 are relatively unsophisticated, so the moments are suspect during times of 
high background and/or high spacecraft potential. Because the determined  
spacecraft potential is not very precise, the magnitude of the low-energy 
ion flow velocity is probably not accurate, but the flow direction is well 
determined.  Tperp and Tpara are obtained from diagonalization of the  
3-dimensional temperature matrix, with the parallel direction assigned 
to the eigenvalue which is most different from the other two. 
The corresponding eigenvector is the symmetry axis of the distribution and 
should be equivalent to the magnetic field direction. The eigenvalue ratio 
Tperp/Tmid, which is provided for each species, is a measure of the symmetry 
of the distribution and should be ~1.0 for a good determination. Several of  
the parameters have a fairly high daily dynamic range and for survey purposes 
are best displayed logarithmically. These parameters are indicated by  
non-zero 'SCALEMIN' values in this file. A quality flag value of 1  
indicates that the values are suspect because of unreliable 
location info.

L0_K0_SPA (spase://NASA/NumericalData/LANL/1990/SOPA/PT60S)
Description
     Electron, proton and helium measurements are taken every 160 ms from one 
of the three telescopes according to the following sequence:  T1, T2, T3, 
T2, T1, T2 etc.  Heavy ion data accumulated from each of the three telescopes 
again according to the timing and sequence above and summed for 10.24 seconds
which is approximately one spacecraft rotation.  SOPA Key Parameters are 
normally averaged over three telescopes for ~ 1 minute (6 - 10.24 second
data accumulation cycles) giving an average over much of the sky.  The time 
associated with each set of Key Parameters is determined by using the time 
(in minutes of the day) at the start of each data collection cycle as an index
into an array of 1440 time slots dividing the day into 1440 one minute 
intervals.  The time reported is the midpoint of each interval.  
     We provide six fluxes:
        Low energy Protons:  75 keV to 400 keV
        High energy Protons: 1.2 MeV to 5 MeV
        Low energy Electrons:  50 keV to 225 keV
        High energy Electrons: 315 keV to 1.5 MeV
        Helium      : ~0.9 MeV to ~1.3 Mev
        Heavy Ions  : ~5 MeV to ~15 MeV (includes carbon, nitrogen,
                       and oxygen
     We also compute two electron temperatures and densities and two proton
temperatures and densities.  These are based on approximately the same energy
ranges as the fluxes given in above and are determined for relativistic
Maxwellian distributions.  
Status of SOPA Instrument 1990-095:  Loss of all ion data as of July 1992
All three thin, front, D1 detectors have failed, having become intolerably
noisy.  The net result of this failure is the complete loss of proton, 
helium, carbon, nitrogen, oxygen and other high Z Key Parameter data from
the instrument.  Since all three thick, back D2 detectors are still 
operating normally, the electron measurements remain only insignificantly 
affected.
Data is flagged with a data quality flag as follows:
   +1 Data is Good
    0 Data is Suspect
   -1 Data is Unusable
