Source file for the World Magnetic Model This is a port of code available from the US NOAA.

The hard coded coefficients should be valid until 2020.

Updated coeffs from .. http://www.ngdc.noaa.gov/geomag/WMM/wmm_ddownload.shtml

NASA C source code .. http://www.ngdc.noaa.gov/geomag/WMM/wmm_wdownload.shtml

Major changes include:

• No geoid model (altitude must be geodetic WGS-84)
• Floating point calculation (not double precision)
• Hard coded coefficients for model
• Elimination of user interface
• Elimination of dynamic memory allocation
