MulensModel.causticswithshear module

class MulensModel.causticswithshear.CausticsWithShear(q, s, convergence_K=0.0, shear_G=0j)

Bases: MulensModel.caustics.Caustics

Caustics structure for a binary lens with shear and convergence.

Attributes :
q: float

mass ratio between the 2 bodies; always <= 1

s: float

separation between the 2 bodies (as a fraction of the Einstein ring)

convergence_K: float

convergence of the lens system

shear_G: complex

shear of the the lens system
