Pulse Height Analyzer Event Summaries (Nonoverlap)


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

Time span: 1967-05-24 to 1969-05-02


This data set consists of cosmic-ray telescope pulse height analyzer data on binary magnetic tapes created on an XDS 930 computer. The data set contains all nonoverlapped, good or fair quality, nonduplicate pulse height analysis events from the three 256-channel pulse height analyzers. The output from these analyzers was obtained for one incident particle every 5.12 s. The data are ordered by satellite orbit revolution number, with multiple files per tape. Each file on the tape contains pulse height analysis data for one orbit. There are a variable number of physical records (each containing 600 binary words) per file. There are three binary words per event and 200 events (logical records) per physical record. In addition, the tapes include the orbit number, range identification, sequence number, and data quality flags.
