CONTENTS OF THIS DIRECTORY
==========================

This directory contains only parts of the distributed library that are really
needed to ACM:

Geomagnetism.h
	Originally named src/GeomagnetismHeader.h in the package distributed by NOAA,
	contains the interface header to the WMM library.

Geomagnetism.c
	Originally named src/GeomagnetismLibrary.c in the package distributed by NOAA,
	contains the actual implementation of the WMM library.

wmm.h
wmm.c
	ACM specific interface module to the WMM library.

The file of the coefficients bin/WMM.COF has been copied into objects/WMM.COF;
this file is valid for dates in the range from year 2015 up to 2019.

It is important to remember that the file of the coefficients WMM.COF ensures
accurate results only in the specified range of years; beyond this range a
warning is displayed.
