- MulensModel is package for modeling microlensing (or μ-lensing) events.
Detailed documentation: https://rpoleski.github.io/MulensModel/
Latest release: 2.7.2 and we're working on further developing the code.
MulensModel can generate a microlensing light curve for a given set of microlensing parameters, fit that light curve to some data, and return a chi2 value. That chi2 can then be input into an arbitrary likelihood function to find the best-fit parameters.
If you want to learn more about microlensing, please visit Microlensing Source website.
Currently, MulensModel supports:
- Lens Systems: point lens or binary lens.
- Source Stars: single source or binary source.
- Effects: finite source (1-parameter), parallax (satellite & annual), binary lens orbital motion, different parametrizations of microlensing models.

Are you using MulensModel for scientific research? Please give us credit by citing the paper published in "Astronomy and Computing" and ASCL reference. For arXiv see link. You should also cite relevant papers for algorithms used. In a typical run that uses binary lenses these will be Bozza (2010) and Skowron & Gould (2012). HERE is a list of papers to cite for various algorithms used in MulensModel.
We have more than a dozen of examples - starting from very simple ones (like plotting a model) to very advanced (like fitting a binary lens model with finite source effect). Please see:
- a list of examples and tutorials,
- description of all microlensing parameters used in MulensModel,
- methods used to calculate magnification in MulensModel, and
- high-level fitting example.
The full documentation of API is at https://rpoleski.github.io/MulensModel/.
The easiest way is to run:
pip install MulensModel
which will download all files and also install all dependencies.
If the above method doesn't work or you would like to see other possibilities, then please see the install file.
