Major overhaul of the WMM Sublibrary, which is now called the Geomagnetism Library. It has been reorganized into 5 categories:
-User Interface
-Memory and File Processing
-Conversions, Transformations, and other Calculation
-Spherical Harmonics
-Geoid
The documentation has been updated. Two new functions were added: MAG_YearToDate and MAG_SphericalToCartesian. Several minor pointer related bugs were fixed as well. |

Changes: As of 2000, the model produced and distributed from the
Web has been named "wmm.cof", with the model epoch contained in the header of the model.
The current model has an additional change to be compliant with Y2K. The publication date
of the model, as shown in the first line (header) of the model is now a four-digit year.
There are no changes in the format of the coefficients. |
