This is a code repository meant to facilitate easy access to galaxy-scale strong lens data.
This repository stores (in python array form) reduced data, PSF models, and lens models for 28 quadruply-imaged quasars. The data are all in the Data module, and the lens models are in the Model module. The lens modeling is intended to be performed with lenstronomy (https://github.com/lenstronomy/lenstronomy).
Notebooks that do lens modeling for 24 systems can be found in notebooks/baseline_lensmodels directory.
This repository also includes functions and methods used for forward modeling quad lenses with dark matter substructure. The functionality is inside the "forward_model.py" file. An example script that shows how to run a dark matter inference with the data stored in this repo can be found in /notebooks/JWST_DM_survey_IV/example_lauch_script_0435.py.
The scripts used for the analysis presented in the JWST lensed quasar DM survey papers III and IV can also be found in the ./notebooks/jwst_DM_survey_IV directory.
When using this repository, please cite JWST lensed quasar DM survey IV Gilman et al. (2025)
