abstract: 'Calculate magnetic field at a given location and time according to the
  World Magnetic Model (WMM). Both the main field and secular variation components
  are returned. This functionality is useful for physicists and geophysicists who
  need orthogonal components from WMM. Currently, this package supports annualized
  time inputs between 2000-01-01 to 2029-12-31. If desired, users can specify which
  WMM version to use, e.g., the original WMM2015 release or the recent out-of-cycle
  WMM2015 release. Methods used to implement WMM, including the Gauss coefficients
  for each release, are described in the following publications: NOAA NCEI Geomagnetic
  Modeling Team and British Geological Survey (2024) <https://doi.org/10.25921/aqfd-sd83>,
