2- and 5-Minute Averaged Electron Count Rates Plotted vs L, on Microfilm


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

Time span: 1964-09-07 to 1967-06-04


This electron spectrometer count rate data set is on one reel of 16-mm microfilm that was generated at NSSDC from 322 plots submitted by the experimenter. The data consist of 2- and 5-min averages of the background-corrected count rates of all five spectrometer channels, plotted on a logarithmic scale vs L (in the range 1.0 to 8.0 earth radii). The 2-min averages are presented only for L values that are less than 3, while the 5-min averages are presented only for L values greater than 3. Also presented on each frame are the beginning and end times, orbit number, and whether the data are for an inbound (apogee to perigee) or an outbound pass of the spacecraft. These data are time ordered and cover approximately 75% of the orbits during the period from September 7, 1964, to June 4, 1967. No additional ephemeris information is presented.
