microlux: Microlensing using Jax

Test Status Documentation Status License: MIT

microlux is a Jax-based package that can calculate the binary lensing light curve and its derivatives both efficiently and accurately. We use the modified adaptive contour integratoin in VBBinaryLensing to maximize the performance. With the access to the gradient, we can use more advanced algorithms for microlensing modeling, such as Hamiltonian Monte Carlo (HMC) in numpyro.

Installation

The PyPI version is coming soon. Currently, You can install this package from the source code in the editable mode.

git clone https://github.com/CoastEgo/microlux.git
cd microlux
pip install -e .

Documentation

The documentation is available at here. See this for more details.
