Pulse Height Data


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

Time span: 1973-11-03 to 1975-03-21


These experimenter-supplied, pulse-height data are on binary magnetic tape created on an XDS 930 computer. Non-zero pulse-height events were extracted from raw experimental data records beginning at a specified time and collected over the following 15 min. At the end of a 15-min period, two or more physical records containing a variable number of events (depending primarily upon solar activity) are written onto tape. The first of these records is a header of 120 24-bit words containing time (in day and fraction of day) and supporting information necessary for the analysis of the data. This information includes a data quality indicator, command status, summarization of coverage and quality of data, selected counting rates, satellite number, and the number of events. The data records contain non-zero pulse heights from the 15-min period described in the header record. The physical records are of variable length with a minimum of 150 words and a maximum of 1020 words. Two 24-bit words represent either a main telescope or low-energy telescope event containing the range identification for a particle, data quality indicator, and the telemetered pulse-height analysis channel reported for the event from detectors 1, 2, and 5.
