This directory contains the WORLDMAP program and data files for the 
Alouette 1, 2 and ISIS 1, 2 satellite missions. The software was provided 
by W.B. Schar (RITSS) and R.F. Benson (GSFC, Code 692). It is based on the 
WORLDMAP program obtained from H.G. James (CRC, Ottawa, Canada).

The interactive FORTRAN program WORLDMAP.FOR will prompt the user for the 
following INPUT parameters: 
	Satellite ID: 	1 - Alouette 1
			2 - Alouette 2
			3 - ISIS 1
			4 - ISIS 2
	Date: 		Year, Day of Year
	Time (UT):	Hour, Minute, Second
The program will generate the following OUTPUT parameters:
	Local Time (LMT), Latitude, Longitude, Height, Geomagnetic
	Local Time, Geomagnetic Latitude, Geomagnetic Longitude,
	Invariant Latitude, Magnetic Inclination (DIP), Solar Zenith
	Angle (CHI), SUN (in or out of sunlight), and the L-value.
