Raccoon cleans low-frequency sinusoidal artifacts (“wiggles”) caused by resampling noise or aliasing in JWST-NIRSpec integral field spectroscopy (IFS) data. The package provides tools to process affected data and to visualize spectra before and after wiggle cleaning. Users can tailor settings to the source morphology or astronomical scene and to characteristics of the observed data (e.g., wavelength range).

Dolphin uniformly models large lens samples. It is a wrapper for Lenstronomy (ascl:1804.012), and features semi-automated modeling of a large sample of quasar and galaxy-galaxy lenses. Dolphin, written in Python, provides easy portability between local and MPI environments.

LensingETC optimizes observing strategies for multi-filter imaging campaigns of galaxy-scale strong lensing systems. It uses the lens modelling software lenstronomy (ascl:1804.012) to simulate and model mock imaging data, forecasts the lens model parameter uncertainties, and optimizes observing strategies.
