MulensModel.binarylenswithshear module¶
- class MulensModel.binarylenswithshear.BinaryLensPointSourceWithShearWM95Magnification(convergence_K=None, shear_G=None, **kwargs)¶
Bases:
MulensModel.binarylens.BinaryLensPointSourceWM95MagnificationThe binary lens with shear and convergence: solutions, images, parities, magnifications, etc.
Uses Witt & Mao 1995 for the binary lens magnification calculation. See py:class:binarylens.BinaryLensPointSourceWM95Magnification
The binary lens with shear and convergence equation is the 9th order complex polynomial.
- Attributes :
- mass_1: float
mass of the primary (left-hand object) as a fraction of the total mass.
- mass_2: float
mass of the secondary (right-hand object) as a fraction of the total mass.
- separation: float
separation between the two bodies as a fraction of the Einstein ring.
- convergence_K: float
External mass sheet convergence.
- shear_G: complex
External mass sheat shear.
Note: mass_1 and mass_2 may be defined as a fraction of some other mass than the total mass. This is possible but not recommended - make sure you know what you’re doing before you start using this possibility.
