Plots of 2-min Averaged Count Rates vs Time (Radiation Belts) on Microfilm


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

Time span: 1964-09-15 to 1966-05-27


This data set consists of time-ordered, 2-min averages of the logarithm of the count rate vs time for each of the five electron spectrometer channels. The data set is on one reel of 16-mm microfilm that was generated at NSSDC from 116 plots submitted by the experimenter. The count rate, which has been corrected for background, may be converted to a flux value by using a conversion factor supplied by the experimenter. Each of the plots presented contains data from all five channels and approximately 3 h of data for that portion of the orbit in the vicinity of the radiation belts. These data cover approximately 60% of the orbits during the period from September 15, 1964, to May 27, 1966. No ephemeris information is presented.
