GCMicrolensing

Tools for simulating gravitational microlensing events with single, binary, and triple lens systems. This package is under active development.

Installation

Prerequisites

This package requires a custom version of TripleLensing with modifications by Gregory Costa Cuautle. The installation process depends on how you obtained this package:

Option 1: From Source (Recommended)

If you cloned this repository, the custom TripleLensing is included and will be installed automatically:

git clone <repository-url>
cd Costa
pip install -e .

Option 2: Manual Installation

If you're installing from a distribution that doesn't include TripleLensing, you'll need to install it manually:

# First install GCMicrolensing
pip install GCMicrolensing

# Then install the custom TripleLensing (instructions to be provided)
# This requires the custom version with Greg's modifications

Usage

from GCMicrolensing.models import OneL1S, TwoLens1S, ThreeLens1S

# Create a single lens model
model = OneL1S(t0=2450000, tE=20, rho=0.001, u0_list=[0.1, 0.5, 1.0])
model.plot_light_curve()

Dependencies

• TripleLensing: Custom version with modifications by Gregory Costa Cuautle
• VBMicrolensing: For binary lens calculations
• Standard scientific Python stack: numpy, matplotlib, scipy, astropy, etc.

Documentation

See the docs/ directory for detailed documentation. This project uses a regular Python packaging workflow. To install the package and its minimal runtime dependencies, execute::

pip install .

The local TripleLensing library will be built and installed automatically as part of this process.

For development a more feature rich environment can be created using the environment.yml file.
