RotateCelestial2Native

class astropy.modeling.rotations.RotateCelestial2Native

Bases: astropy.modeling.rotations.EulerAngleRotation

Transformation from Celestial to Native to Spherical Coordinates.

Defines a ZXZ rotation.

Parameters:

phi, theta, psi : float

Euler angles in deg

Attributes Summary

Methods Summary

__call__(alpha_C, delta_C[, model_set_axis])	Evaluate this model using the given input(s) and the parameter values that were specified when the model was instantiated.
evaluate(alpha_C, delta_C, phi, theta, psi)	Evaluate ZXZ rotation into native coordinates.

Attributes Documentation

inputs = (u'alpha_C', u'delta_C')

inverse

outputs = (u'phi_N', u'theta_N')

Methods Documentation

__call__(alpha_C, delta_C, model_set_axis=None)

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

classmethod evaluate(alpha_C, delta_C, phi, theta, psi)

Evaluate ZXZ rotation into native coordinates.

This is like RotateNative2Celestial.evaluate except phi and psi are swapped in ZXZ rotation.
