# EulerAngleRotation¶

class astropy.modeling.rotations.EulerAngleRotation(phi, theta, psi, axes_order, **kwargs)[source] [edit on github]

Bases: astropy.modeling.rotations._EulerRotation, 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.
