Description

This heavy isotope spectrometer data set is on binary magnetic tape created on a PDP 1 computer. The physical record length varies but is always less than 8000 bytes. The first physical record on each tape contains 10 64-byte header records, 28 276-byte data records, and a 4-byte logical record that flags the end of the physical record and contains the physical record number. The following physical records contain the data records and an end-of-record flag. The last physical record on each tape contains a string of 100 4-byte logical records that flag the end of the tape, and each contains the number of physical records on the tape. Each header record contains the tape name, execution date, and program version date. The data records contain 1-h averaged data for the period following the failure of a readout logic component. This caused the degrading of pulse-height-analysis data and hodoscope information, but counting rate data were not affected. Consult the data set documentation for the details of the changes caused by this failure. The data records contain: the year, day of year (Jan.1=1), and hour of day; an insufficient data or operational mode flag; the number of H events in each of the first four energy ranges (up to 11.8 MeV/nucleon) and the number of He events in each of the first five energy ranges (up to 20.4 MeV/nucleon); the sum of the low-Z (H and He) counting rates (counts/s) from all operational energy ranges, the low-Z counting rates and the hi-Z counting rates from each of the first five energy ranges, the single-detector counting rates from each of the first seven detectors of the instrument, and the statistical uncertainty for each of the above counting rates (counts/s); the differential flux of H in each of the first four energy ranges and the flux of He in each of the first five energy ranges, and the statistical uncertainty for each of these fluxes; the lifetime for the analyzed low-Z events (s); and the fraction of events that trigger two or more nonadjacent strips on either of the first two detectors (M1 or M2), called the multiple hodoscope fraction. Consult the data set documentation for many details concerning this data set.
