Ryle-Vonberg 24-Hour Data


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

Time span: 1973-07-12 to 1975-06-28


These data are the basic data base for the Ryle-Vonberg receiver investigation. Each file contains four days of data. The tapes are IBM standard labels. The logical record length is 908 bytes, consisting of a four-byte logical record control word and 904 data bytes. The physical record length is 31,784 bytes, consisting of a control word and 35 logical records. Each logical record contains day and date; channel number (i.e., frequency); X, Y, and Z spacecraft vectors; right ascension and declination of the upper V-antenna; coarse and fine data samples from both the RV-1 and RV-2 receivers; and RV ambient temperature. Each frequency is selected for 15.4 s before stepping to the next, and each logical record contains a set of the parameters for each frequency step in a given sequence.

Twenty-four-hour plots of these parameters are available on microfilm (NSSDC data set PSFP-00009).
