IMP-8 Data Processing System Program

User's Guide

1. GENERAL DESCRIPTION

   The IMP-8 Data Processing System creates an encyclopedia file for
   the Cosmic Ray experiment (Experiment Number 52) on board the IMP-8
   spacecraft.  Decom files, created by IPD, parameter cards, and a file
   catalog are input to the program.  Encyclopedia files, and an updated
   file catalog are the output.  When full, each encyclopedia file will
   contain three 4-day intervals of data.

   Interval numbering follows the same system as IMP-7; that is, interval
   number 1 begins at 0000 hours on Sept. 23, 1972.  Thus the first data
   from IMP-8 will probably correspond to interval 101. The reel sequence
   numbers are determined by the interval numbers. For encyclopedia files,
   reel sequence numbers are of the form

   NNNNNNDUU

   where NNNNNN is the number of the file in the series:
         number 1 contains intervals 1-3
         number 2 contains intervals 4-6
         number 34 contains intervals 100-102

         D is the duplicate indicator; 0 is an original and 1 is a duplicate.

         UU is the update number; when the file is created, UU is equal to 01,
         it is incremented by one each time the file is updated or reprocessed.

         Thus, if the first interval processed is 101, the first encyclopedia
         file will have a reel sequence number of 34001.
