Dear Pierre-Simon
That routines performs a trasformation of coordinates from/to
geographical cartesian coordinates to/from geomagnetic cartesian coordinates.
We mean by geographical cartesian coordinates a system in which the the z-axis
coincides with the earth rotation axis , while in the geomagnetic system the z-axis
passes through the magnetic poles

The code of geogmg is available with the rest of FLUKA source code.
This can be requested according to what established in the additional registration procedure
which is referred in the download page of FLUKA web site

Best regards
