MulensModel.pointlenswithshear module

class MulensModel.pointlenswithshear.PointLensWithShear(parameters=None)

Bases: MulensModel.pointlens.PointLens

Lens of point mass plus shear and convergence, i.e., Chang-Refsdal lens.

This lens was first considered by Chang and Refsdal (1979; Nature, 282, 561).

Keywords :

parameters: ModelParameters

Parameters of the model.

get_point_source_magnification(trajectory)

Calculate point source magnification for the lens composed of a single mass plus a mass sheat.

Arguments :

trajectory: Trajectory object

Trajectory of the source.

Returns :

pspl_magnification: np.ndarray

The point-source–point-lens magnification for each point specified by trajectory.
