  25  These values are collected from GeodTest which is associated with GeographicLib:
  26      https://zenodo.org/record/32156
  27
  28  The conversion to C++ array format is done using this Python script:
  29      https://github.com/adl1995/boost-geometry-extra/blob/master/geographiclib-dataset-parse-inverse.py

  31  Geodesic scale (M12) is absent from the GeodTest dataset, so it is manually generated
  32  using GeographicLib using this C++ script:
