 Making the output useful to the wider community is one of MAG's primary
  goals.
  In this release MAG includes Gauss coefficients in the output file.

  MAG uses fully-normalized, complex-valued spherical harmonics for its magnetic
  field and other variables.
  These harmonics are packed into one-dimensional arrays for optimal computation
  and they are also made non-dimensional in MAG.
