Proton, Alpha Particle and Electron Count Rates

Description

These data consist of a master file of the particle count rate data (counts/9.875 s) from investigations 69-097A-02, 69-097A-04, and from a portion of the data from 69-097A-03 (corresponding to low invariant latitudes). The data are in chronological order on binary magnetic tapes written on an IBM 360.

At the beginning of each tape there is a tape identification record which is followed by a variable number of physical records. Each orbit of the satellite is identified in the pass header physical record, and is followed by the data records. In addition to the orbit number, the pass header record contains the date and time of the pass (year, day, second of the beginning and end of the pass), station name, and magnetic activity index (Kp).

Each data record contains the proton, electron, and alpha particle count rates from the three experiments. In addition, the record contains the following: the date and universal time of the measurements (day, hour, minute, and second), local time, magnetic local time, orbit number, geographic latitude and longitude, altitude, right ascension, declination, magnetic latitude and longitude, geomagnetic field strength B, McIlwain's L-shell parameter, invariant latitude, geocentric radial distance (Earth radii), angle between the satellite axis and magnetic field, azimuth with respect to the magnetic field, solar aspect angle, azimuth with respect to the sun, the three spacecraft spin axis components, the three local magnetic field (X, Y, Z) components, and various housekeeping parameters.
