After the structure is centered, it is also aligned to a set of orthogonal axes. This variable decides which set of axes to use. Only implemented for 3D, in which case the default is inertia; otherwise none is default and the only legal value.
Do not rotate. Will still give output regarding center of mass and moment of inertia.
The axis of inertia.
Pseudo-axis of inertia, calculated considering all species to have equal mass.
The larger axis of the molecule.
