input_names = ['phi_N', 'theta_N']

Methods Documentation

__call__(phi_N, theta_N)

classmethod evaluate(phi_N, theta_N, phi, theta, psi)

Evaluate ZXZ rotation into celestial coordinates.

Note currently the parameter values are passed in as degrees so we need to convert all inputs to radians and all outputs back to degrees.
