LEPEDEA Count Rates and Fluxes

NSSDC ID: SPMS-00212

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

Time span: 1969-06-28 to 1970-08-19

Description

This experimenter-supplied data set contains low-energy proton and electron differential energy analyzer data on BCD magnetic tapes. Each record contains data for one full LEPEDEA cycle (5.8 min). These data consist of count rates for protons and electrons for each of 15 energy windows for each of four angular sectors. The data also contain energy bandpass fluxes and integral fluxes for each sector, energy window, and species. Sectored Geiger-Mueller tube count rates and background LEPEDEA count rates are also given. Supporting data found in each record include LEPEDEA look-direction information and spacecraft ephemeris information. Look-direction information is given in GSM, GSE, and geocentric equatorial inertial coordinate systems. The angle between the magnetic vector and the field of view is also given. Spacecraft ephemeris information includes geographic latitude, longitude, and radial distance; B, L, and related variables; right ascension, and declination; GSM, GSE, and celestial inertial coordinates; and geographic and geomagnetic local times. Additional data include spacecraft spin rate and direction, sun direction, and housekeeping parameters.
