90 Minute and 24 Hour Survey Plots on Microfiche


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

Time span: 1978-08-13 to 1987-02-07


These microfiche were provided by the investigator. Each fiche card covers 24 h of data, displayed in 72 labeled frames. These frames contain 24-h summaries and 90-min plots. One frame notes the date of the data on the card and seven frames plot 24-h summaries of data. These seven include three frames of housekeeping data (power drawn by each receiver and temperature of the electronics) and four frames of scientific parameters. The four parameters are receiver output signals for both 10 kHz (denoted by GB) and 3 kHz (PB) bandwidths, for both the spin-plane (S) 90-m tip-to-tip antenna and the spin axis (Z) antenna, whose length was increased over 6 months by steps of about 3 feet from 0 to 18 feet. These four parameters are labeled ZGB, ZPB, SGB, and SPB. Each of these parameters is plotted at 12 frequencies per frame. The 12 frequency steps for the wideband receivers (GB) are 1980, 1000, 513, 360, 233, 160, 123, 94, 72, 60, 50, and 41 kHz. For the narrow band receivers (PB), the 12 frequencies are 1000, 466, 290, 188, 145, 110, 80, 66, 56, 47, 36, and 30 kHz. The other 64 frames display the same four parameters in 90-min plots covering the same day.
