IMP 8 UMD EECA 10.92m Rates, PHA

Metadata Updated: April 10, 2026

This data set, from the Electrostatic Energy-Charge\nAnalyzer (EECA) part of the U. Maryland experiment on IMP 8, contains \ncount rate and pulse height data enabling the computation of 10.92-min \nresolution fluxes of: singly ionized ions in 5 energy/charge windows of \nlower limits between 130 and 740 keV/Q; doubly charged ions in the same \n5 keV/Q windows plus another at 65 keV/Q; ions with charge states between \n5 and 8 in the same 6 keV/Q windows as for doubly charged ions plus \nanother at 37 keV/Q; ions with charge states above about 10 at 37 and 65 \nkeV/Q windows; 600-860 keV electrons. Some of the modes are spin \nintegrated while others are given in 90 deg quadrants about the spacecraft \nspin vector (which is normal to the ecliptic plane). The data set was \ncreated at NSSDC from the U.Md.-provided "summary tapes" (NSSDC IDs \nSPHE-00170 and 73-078A-03C) by dropping engineering data, dropping data \nfrom the ULET portion of the overall experiment (the ULET instrument \nfailed in 1978), and converting the remaining time, spacecraft position, \nand EECA instrument data from binary to ASCII representation. The data \nare available via ftp in 1- month files of variable lengths in the 3-6 MB \nsize range.
