Tools for end-to-end reduction of JWST exoplanet observations

vMPT — visual MSA Planning Tool. Interactive Bokeh app for hand-picking JWST/NIRSpec MSA shutter configurations on target-field images. Exports an APT-loadable bundle in the eMPT format.

Resolution measurement for the JWST NIRSpec

Routine used to correct the 1/f correlated noise observed in the detector images of the JWST instruments

AssetForJwstNirspecFs is a Julia package to extract spectrum from JWST/NIRSpec Fixed Slit data.

JWST background tool - but much faster for extragalactic use ⚡

Hot-Saturn atmosphere study pairing a timing-adjusted TESS transit with public JWST/NIRSpec transmission spectroscopy, including the prominent carbon-dioxide feature and reproducible spectral diagnostics.

Habitable-zone rocky-exoplanet atmosphere study using decontaminated JWST/NIRSpec PRISM transmission spectroscopy to test spectral flatness and clearly separate measured constraints from atmospheric interpretation.

Rocky super-Earth atmosphere study combining real TESS transit photometry with JWST/NIRSpec G395H transmission spectroscopy, testing a largely flat spectrum and what low-metallicity hydrogen atmospheres can be excluded.

JWST/NIRSpec microshutter-array diagnostic for shutter behavior, light leakage and spectroscopy systematics, using reproducible instrument-focused analysis to examine data-quality impacts and measurement limits.

Hot-Saturn atmosphere study using public JWST/NIRISS and NIRSpec spectra to examine water-rich transmission features and morning/evening terminator asymmetry with explicit statistical diagnostics.

Temperate sub-Neptune atmosphere audit combining public JWST NIRISS, NIRSpec and MIRI spectra to test disputed molecular features, inter-instrument offsets and the evidence limits around K2-18 b's atmospheric interpretation.

Ultra-hot Jupiter atmosphere study using phase-resolved JWST/NIRSpec G395H emission spectroscopy to measure day-night brightness-temperature contrast, with reproducible uncertainty propagation and archive-backed system context.

Open utilities for planning JWST NIRSpec MSA observations

Earth-sized rocky-exoplanet atmosphere test using public JWST/NIRSpec G395H transmission spectroscopy, comparing candidate atmosphere models with explicit chi-square, degrees-of-freedom and p-value diagnostics.
