This table has for purpose to define the radiation periodicity in 3D.

The three first columns correspond to the coordinates of an invariant Point. Vx,Vy,Vz correspond to the vector of an axis and teta is the angle of the periodicity of rotation around the above axis.

Be aware that the indicated angle must give 360 degres when multiply by a integer. Typically 60 degres or 120 degres are valid angles, but 55 degres is not.
