Tape Playback Electron Data, 0.05 to 1.2 MeV

NSSDC ID: SPMS-00495

Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1968-03-30 to 1971-02-14

Description

This electron count rate data set contains all available significant playback data from this experiment for the inclusive time period on experimenter-generated, magnetic tapes with IBM 360 eight-bit bytes. An experimenter-provided program that calculates the fluxes of particles is available. The program in its current form is expensive to run, but contains calibration tables, etc., necessary to reduce the data. The physical record size of these tapes is 4088 bytes. For each physical record, the first eight bytes are sensor calibration data, followed by up to 255 logical records of 16 bytes each containing data quality flags, channel number, time data flags, mode flags, and the electron count rates. Since this experiment was designed to study magnetospheric disturbances, data from times when no change in the count rate was detected are not included on these tapes. NSSDC has found physical records where the first seven data records are filled with irregular-looking data that do not fit this format, followed by apparently good data for the rest of the physical record. Physical records containing fewer than 255 logical data records are padded out with blanks.
