Fine-Time Scale 100 Hz, 400 Hz, and 30 KHz Electric Field Amplitudes


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

Time span: 1969-11-29 to 1970-03-11


This magnetic tape, made at NSSDC from experimenter-supplied data tapes, contain all probably correct data from the Pioneer 9 experiment in both reduced and packed raw form. Logical tests were made on the time words during tape copying to assure that scrambled, and thus unintelligible data records, were not retained. Records containing all zeros were not deleted, and some files may contain no data records. The data are on a binary tape with numerous files. Each file contains a 648 character BCD header record followed by 450 binary 36-bit word data records (2700 characters). Each physical record contains one logical record. Each logical record includes eight sets of eight 100-Hz measurements, sixty-four 400-Hz and 30-kHz amplitude measurements, times for each measurement, and satellite ephemeris.
