EulerAngleRotation

class astropy.modeling.rotations.EulerAngleRotation

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.

Methods Documentation

__call__(alpha, delta, model_set_axis=None)

Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.

eval(*args, **kwargs)

Deprecated since version 1.0: The eval function is deprecated and may be removed in a future version. Use EulerAngleRotation.evaluate instead.

Evaluate the model on some input variables.

evaluate(alpha, delta, phi, theta, psi)

Evaluate the model on some input variables.
