Ryle-Vonberg 24 Hour Plots


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

Time span: 1974-10-31 to 1977-04-26


This data set is contained on 16-mm microfilm. It summarizes the observations made with the Ryle-Vonberg receivers (RV-1 and RV-2) on RAE-B. Each frame represents the observations taken on a particular day (shown in yy/mm/dd format in the lower left-hand corner) at a particular frequency, one of the nine frequencies of operation, from 0.45 to 9.18 MHz. The upper plot is for RV-1, connected to the upper V-antenna; the lower plot is for RV-2, connected to the lower V-antenna. The fine and coarse measurements of the relative antenna temperature (called calibration temperature) are plotted logarithmically as squares and dots, respectively, on a scale that covers 60 dB, with horizontal grid lines at decade intervals. Vertical grid lines are drawn every hour and labeled.

The digital version of this dataset is available as NSSDC data set PSFP-00075.
