Thread on our new paper on arxiv today! We stumbled across a weird sinusoidal systematic that we think appears in every observation from the NIRISS instrument on JWST. We derive a correction and see how much it impacts exoplanet spectra. (1/N) #astro #exoplanets 🔭🧪 arxiv.org/abs/2606.11983

Calibration of an Analog-to-Digital Conversion Nonlinearity in JWST/NIRISS

We quantify an unusual flux-dependent systematic which is periodic in raw counts in flight data from the James Webb Space Telescope's Near Infrared Imager and Slitless Spectrograph (JWST/NIRISS), used...
