exoTEDRF (Exoplanet Transit and Eclipse Data Reduction Framework) reduces and analyzes JWST exoplanet time series observations. The code is modular and tunable, which makes it easy to run multiple reductions of a given dataset, and therefore ascertain whether the spectral features driving atmosphere inferences are robust or are sensitive to the peculiarities of a given reduction. exoTEDRF has full support for TSOs with NIRISS/SOSS and can run the ATOCA extraction algorithm (ascl:2502.016) to explicitly model the SOSS order overlap.

APPLESOSS (A Producer of ProfiLEs for SOSS) builds 2D spatial profiles for the first, second, and third diffraction orders for a NIRISS/SOSS GR700XD/CLEAR observation. The profiles are entirely data driven, retain a high level of fidelity to the original observations, and can be used as the specprofile reference file for ATOCA (ascl:2502.016). They can also be used as a PSF weighting for optimal extractions.

ATOCA (Algorithm to Treat Order Contamination) extracts and decontaminates spectroscopic images with multiple sources or diffraction orders. For all orders and sources, the package takes the wavelength solutions, the trace profiles, the throughputs, and the spectral resolution kernels as input. From these, ATOCA simultaneously models the detector and extracts the spectra.
