IMP Data Base Time Study Program

User's Guide



1. GENERAL DESCRIPTION

   The IMP Data Base Time Study (DBTIME) is to systematically scan
   and validate the IMP compressed CNTS/PHAS data files, then provide
   a history of time consistency, missing data (data gaps) or any   
   overlap data encountered during the data scan.

3. PROCESSING ENVIRONMENT

   The IMP Data Base Time Study program (DBTIME) is developed on an Sun
   workstation Sun 4.1.4 operating system. The source codes are written
   in Sun FORTRAN language. A local I/O system FTIO package was developed.
   A local shell program was developed to execute the IMP DBTIME program.
