200-eV Electron Count Rate Plots on Microfilm


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

Time span: 1971-02-06 to 1971-03-12


This data set consists of 35-mm microfilm generated at NSSDC from 18 hardcopy plots submitted by the experimenter. Each plot contains 2 day of 5-minute-averaged, 200 eV electron count rates (counts per 1.2 sec - conversion to flux (per sq cm ster eV) effected by multiplication by 100). This mode was chosen because it includes the peak in the plasma sheet electron spectrum and portions of the photoelectron and magnetosheath electron spectrums. The plots include the time period February 6 to March 12, 1971 which contains the first orbit of the moon about the earth after the placement of the instrument on the moon. The experiment has marked on the plots physically significant transitions (e.g., from the magnetotail to the magnetosheath) and the monthly 18-hr period of solar ultraviolet-induced photoelectron contamination. The experimenter also has generated similar plots for other times and other modes that were scientifically interesting to him, but not on a routine basis. All his data are to be found in magnetic tape data set 71-008C-08A.
