Injun 5 Master File Data

Description

This collection consists of data from all four instruments flown on the Injun 5 spacecraft. The data are in time-ordered, BCD format originally written on a UNIVAC 418 computer. The data are 696 characters per logical record, 10 logical records per physical record, and a variable number of physical records per file.

The data for the LEPEDEA experiment are in millivolts (no documentation as to the conversion to counts per second is provided). The data for the solid-state particle detector is also in millivolts (documentation on the conversion to counts per second is available). The data for the retarding potential analyzer have three telemetry channels for the output from the electron sensor, the ion sensor, and the event monitor. The VLF data contain signal strength information for the six frequencies received by the VLF receiver.

Included with the detector outputs, these data contain universal and local times, orbit number, geographic coordinates (longitude, latitude, and radial distance), geocentric equatorial inertial coordinates (right ascension of satellite, velocity vector right ascension, declination and magnitude of the satellite velocity, magnetic field right ascension and declination, and celestial right ascension and declination of the sun), geomagnetic coordinates (longitude, latitude, equatorial distance to line of force, and local time of satellite), real geomagnetic-field values (McIlwain's L-shell parameter, magnitude, B/Bo, and invariant latitude), sun eclipse times (times to next sunrise and sunset), and magnetic attitude of the satellite (magnetometer measurements in the X, Y, and Z directions).
