Plots of Particle Count Rate Data on Microfilm


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

Time span: 1967-07-19 to 1968-12-31


This data set consists of particle count rate data plotted on 35-mm microfilm. This is a complete set of partially reduced data submitted by the experimenter. The coverage is greater than 90%. Six plots are given for each 12-h period (0000 to 1200 or 1200 to 2400 GMT). These plots contain, as a function of time, (1) the count rates of GM1 for each sector, (2) the count rates of PN1 for each sector, (3) the count rates of GM2, GM3, PN2, and GM1 (GM1 summed over all sectors), (4) the count rates of PN1, PN2, and PN4 of the SSD (PN1 summed over all sectors), (5) the average counting rate (G1AV) of GM1 for sectors I, II, and IV, the counting rate of GM1, sector III, from solar X rays (G1X), and the difference between the count rates of GM3 and GM2, and (6) the coefficients describing first order Fourier fits to the data from PN1 and GM1. The curves fitted to the PN1 and GM1 data were of the form a(1+b cos(d-e)), where d is the spacecraft rotation angle.
