JDISCS | Data

JDISCS MIRI-MRS pipeline.
Our reduction follows the methodology introduced in Pontoppidan et al. (2024) and is continuously updated to the latest JWST pipeline and reference files. We process data to calibrated 3-D cubes, remove background via nodded pairs, and extract 1-D spectra with wavelength-scaled apertures. To suppress high-frequency detector fringes without filtering out real molecular lines, we apply empirical relative spectral response functions (RSRFs) built from spaxel-matched calibrators: bright asteroids across Channels 2–4 and a standard star in Channel 1. Each science dither is divided by the corresponding calibrator RSRF and combined with robust clipping, yielding high-contrast spectra with stable spectrophotometry. The result is a uniform, high-S/N data set optimized for dense mid-IR molecular forests and comparative chemistry across disks.

Access Data 

All extracted 1D spectra from programs in Cycle 1, reduced with the JDISCS pipeline, are publicly available via the Spectroscopy of Exoplanet-forming Disks database (SpExoDisks).
