Welcome to IMP page

OVERVIEW

The Interplanetary Monitoring Platform (IMP-8) satellite constitute
an overall program to study the near-interplanetary region, the outer
portions of the earth's magnetosphere, and the interactions of the sun-
earth system. This document describes the data processing and analysis
program systems for the cosmicra-ray experiments onboard the IMP-8
spacecraft, the data type and the available data in the database at
NSSDC and backup of database at UniTree.

README.TXT

This is an overview about the information of the IMP-8  Goddard Medium
Energy (GME) on NASA Data Archive and Distribution Service (NDADS).

The source codes of each program are written in Sun FORTRAN or C languages. The 
program is developed on a Sun 4.1.4 operating system. A makefile which generates
the object files and executable programs, is provided. Also a user's guide of 
each program which provides the general description and input parameters
informations is provided. A local developed shell program executes the program.

Each zipped tar program file contains the source codes of each routine, user's
guide, makefile, IMP-8 catalog file, a local developed I/O system FTIO package
source file.

Each IMP-8 CNTS/PHAS/MATR data file covers 4 days data in compressed ieee
binary format.

The documents include the IMP-8 CNTS/PHAS/MATR data type specification.

CNTS.TXT
