IMP 8 UMD EECA 10.92m Rates, PHA

This data set, from the Electrostatic Energy-Charge
Analyzer (EECA) part of the U. Maryland experiment on IMP 8, contains
count rate and pulse height data enabling the computation of 10.92-min
resolution fluxes of: singly ionized ions in 5 energy/charge windows of
lower limits between 130 and 740 keV/Q; doubly charged ions in the same
5 keV/Q windows plus another at 65 keV/Q; ions with charge states between
5 and 8 in the same 6 keV/Q windows as for doubly charged ions plus
another at 37 keV/Q; ions with charge states above about 10 at 37 and 65
keV/Q windows; 600-860 keV electrons. Some of the modes are spin
integrated while others are given in 90 deg quadrants about the spacecraft
spin vector (which is normal to the ecliptic plane). The data set was
created at NSSDC from the U.Md.-provided "summary tapes" (NSSDC IDs
SPHE-00170 and 73-078A-03C) by dropping engineering data, dropping data
from the ULET portion of the overall experiment (the ULET instrument
failed in 1978), and converting the remaining time, spacecraft position,
and EECA instrument data from binary to ASCII representation. The data
are available via ftp in 1- month files of variable lengths in the 3-6 MB
size range.
