EulerAngleRotation
[source] [edit on github]¶ Bases:
astropy.modeling.Model
Implements Euler angle intrinsic rotations.
Rotates one coordinate system into another (fixed) coordinate system. All coordinate systems are right-handed. The sign of the angles is determined by the right-hand rule..
Parameters: phi, theta, psi : float
“proper” Euler angles in deg
axes_order : str
A 3 character string, a combination of ‘x’, ‘y’ and ‘z’, where each character denotes an axis in 3D space.
