Atmospheric Reconnaissance of TRAPPIST-1 f with JWST NIRISS SOSS: No Evidence for the Transit Light Source Effect

Description of files combined_transit_spectrum.ecsv Combined (five-visit) transit spectrum (Figure 3, panels a and b). extracted_spectra_abs-flux-calibrated_vis*_order*.h5 Absolute-flux-calibrated spectra of each visit and each spectral order. exoTEDRF pipeline. ldc_vis*.ecsv Max-likelihood, median, and 1-sigma lower and upper uncertainties on quadratic limb darkening coefficients (q1, q2) of each visit and each spectral order. spectra_visit*_ord12.h5 Non-absolute-flux-calibrated spectra of each visit. SOSSISSE pipeline. Used for the transit light curve fit and transit spectrum analysis in the article. This file also contains Halpha luminosities as a function of time, broadband ("white") light curves, as well as spectral trace morphology metrics (dx, dy, ddy, dtheta) and their uncertainties. tlse_model_vis*.txt Retrieved transit light source effect model for each visit: Median, +/- 1 sigma, and +/- 2 sigma. All five visits were fitted simultaneously (common planetary radius and quiet stellar photosphere temperature), and no planetary atmosphere model was included. transit_spectrum_vis*.ecsv Transit spectrum of each visit (Figure 2, panel a) . Spectral order 2 is the first data point. load_files.py Example code that shows how to open each file.
