Common-mode spectra computed from the fiducial temperature flare spectra, shown for each combination of NIRISS and NIRSpec and empirical and RADYN-based pipelines. The smooth evolution of common-mode spectra with temperature motivates our interpolation of common modes from the grid values. Also note the dip in the NIRSpec modes at ∼1.4 μm
