4u'''A pure Python implementation of a biaxial and U{triaxial reference ellipsoid for the 

5Earth<https://link.Springer.com/article/10.1007/s00190-023-01717-1>} with conversion 

6between geodetic lat-, longitude with ellipsoidal height C{h} and (geocentric) cartesian 

7X, Y, Z with orthometric height C{H} using bilinear interpolation of quasi-geoid height 

8C{axN} in bi- and trixial, C{1-degree} grids.
