super(ExternalShear, self).__init__(centre=(<NUM_LIT:0.0>, <NUM_LIT:0.0>), phi=phi, axis_ratio=<NUM_LIT:1.0>)<EOL>self.magnitude = magnitude<EOL>
An external shear term, to model the line-of-sight contribution of other galaxies / satellites.

Parameters
----------
magnitude : float
    The overall magnitude of the shear (gamma).
phi : float
    The rotation axis of the shear.
