Plots of 2-min Averaged Pulse Rates vs Spacecraft Radial Distance on Microfilm


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

Time span: 1964-09-07 to 1967-06-04


This data set consists of time-ordered, 2-min averages of the number of normalized ionization chamber pulses per second times 1000, plotted on a logarithmic scale vs spacecraft radial distance (R) in earth radii. The data set is on one reel of 16-mm microfilm that was generated at NSSDC from 441 plots submitted by the experimenter. Each frame presents approximately 20 h of playback data for R values between 1 and 23. Also presented on each frame are the beginning and end times and an indication of whether the data are for an inbound (apogee to perigee) or an outbound pass of the spacecraft. Approximately 60% of the orbits during the period from September 7, 1964, to June 4, 1967, are represented in this data set.
