Radio Mapping Data Pool Plots on Microfilm


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

Time span: 1978-08-12 to 1987-02-07


These data are contained on 35-mm microfilm reels. The data are plotted vs time in sets of 10 types of plots for each day. Each type of plot shows the magnetic field magnitude, flags indicating when the spacecraft maneuvering unit was on, and the spacecraft position in GSE coordinates (in Re) at a specified time during the day, plus outputs of the investigator's quick-look algorithms for one of the following experiments: solar wind plasma (78-079A-01A), magnetic fields (-02A), low-energy cosmic rays (-03A), medium-energy cosmic rays (-04A), cosmic ray electrons and nuclei (-06A), plasma waves (-07C), energetic protons (-08D), interplanetary and solar electrons (-09C), radio mapping (-10A), and X-ray and gamma-ray bursts (-14D).

The radio mapping data are plots of 128-s averages of the output receiver voltages from the spin-plane antenna with 10 kHz bandwidths at 1000 kHz and 233 kHz. (If only 3 kHz bandwidth measurements were made by the instrument, these are plotted and the lower frequency is 188 kHz. There is no flag on the plots to denote this.)

The average voltage measures the strength of the signal. The rms values are a good indicator of the degree of modulation present; the larger the rms value, the more deeply modulated is the signal, denoting a narrow source near the spin plane. The full data record is needed for direction finding.
