Left: outline of the custom spectral extraction pipeline used to generate absolute-flux-calibrated time-series spectra. Right: intermediate data products generated at various stages throughout the reduction process: (A) relative flux-calibrated spectral time series produced by Eureka!; (B) flux-calibrated and exposure-averaged spectra produced by the jwst pipeline; (C) master calibration factor array; and (D) absolute-flux-calibrated spectral time series. These time-series spectra include a few visible outlier integrations, which are noted in Table 1 and excluded from all subsequent analysis.
