 ### Citation
 
-If you make use of `Herculens`, please cite [Galan et al. 2022](https://ui.adsabs.harvard.edu/abs/2022A%26A...668A.155G/abstract). If you use the [`CorrelatedField`](https://github.com/Herculens/herculens/blob/main/herculens/GenericModel/correlated_field.py) model, please also cite [Galan et al. 2024](https://ui.adsabs.harvard.edu/abs/2024arXiv240218636G/exportcitation).

 ### Special mention regarding Lenstronomy
 Part of the `Herculens` code originates from the open-source lens modeling software package [`lenstronomy`](https://github.com/sibirrer/lenstronomy), described in [Birrer et al. 2021](https://joss.theoj.org/papers/10.21105/joss.03283) (and references therein). In every source file, proper credits are given to the specific developers and contributors to both the original `lenstronomy` (up to version 1.9.3) and `Herculens`.
