Description

These experimenter-supplied tapes are multifiled, created in IBM 360 representation. Each file contains pool data for a 3-day period. Physical records are fixed length at 3240 bytes. The first record of each file is a label containing satellite ID number; year, day of year, and seconds of day for both the start and end of the file; spacecraft clock at start of file; group number; minimum and maximum value of spin period within the file(s); magnetometer Z-axis offset; number of estimates made for Z offset; alpha and group number used to determine Z offset; and bit rates.

The label record is followed by a number of data records containing day of year and seconds of day, spacecraft clock at start of record, bit rate, dummy record indicator, time line indicator, data record number, satellite position in GSE coordinates, spin period average, and outputs of investigators' quick-look algorithms for the following experiments: low-energy cosmic rays (78-079A-03B), magnetometer (-02B), radio mapping (-10B), interplanetary and solar wind electrons (-09B), X-ray and gamma-ray bursts (-14C), solar wind plasma (-01B), plasma waves (-07B), medium-energy cosmic rays (-04B), energetic protons (-08B), and cosmic ray electrons and nuclei (-06B).

The solar wind plasma data include ion pseudo-density (particles/cc), solar wind pseudo-speed, and solar wind pseudo-flow angle, at 5-min intervals.

The magnetometer data include the field components (along the spin-axis, along the satellite-sun line, and along the third orthogonal axis), plus the magnitude and direction of the total field vector, given at 64-s intervals.

The low-energy cosmic ray data, given at 15-min intervals, include proton fluxes in three channels from 0.17 to 20 MeV, alpha particle fluxes in the range 0.12 to 0.25 MeV, and fluxes of particles with Z>2 and energies >0.1 MeV/nucleon.

The medium-energy cosmic ray data include fluxes of particles in the ranges 4 to 57, and 18 to 70 MeV/nucleon, at 15-min intervals. These data were not available from August 1979 to January 1980.

The cosmic ray electron and nuclei data include the count rate of 5 to 150 MeV electrons, at 30-min intervals.

The plasma wave data include the maximum voltages at 31 Hz, 1 kHz, and 31 kHz, and the antenna status, at 5-min intervals.

The energetic proton data, given at 20-min intervals, include proton fluxes in 2 ranges from 78 to 1400 keV, an isotropy index, and qaundrant.

The interplanetary and solar electron data contain fluxes of electrons above 15 keV, at 5-min intervals. These data were replaced by fill data when the experiment failed on November 22, 1979.

The radio mapping data are the average voltages and their rms values at both 200 and 1000 kHz, at 2-min intervals. The averages are made of all the S B samples at the selected frequency which were obtained in successive 128 second intervals (one major frame at the top data rate). The tape record contains 30 averages (one "ISEE hour") at 1000 kHz, each followed by its rms value, after which come 30 averages at 233 kHz, each followed by its rms value. (if only N band observations are being made, averages are of all S NB samples, and the lower frequency is 188 kHz. There is no flag on the tape to denote this.) The average voltage measures the strength of the signal. The rms values are a good indicator of the degree of modulation present; the larger the value, the more deeply modulated is the signal, denoting a narrow source near the spin plane. The full data record is needed for direction finding.

The X-ray and gamma-ray burst data include count rates for 20 to 37 keV gamma rays at 5-min intervals.
