Top: peak flare spectrum of each event overlaid with the best-fit RADYN model, where fits are color-coded by reduced χ² value. The full model grid is shown for reference in gray, where each gray model is scaled by the filling factor of the highlighted model. The models qualitatively describe the line and 0.82–2.83 μm continuum emission, but predict a large Paschen jump not present in the observations. The daggers denote NIRSpec flares. Bottom: a close-up of the best-fit RADYN line models for the F4 event compared with the NIRISS data. Although not included in RADYN, Pγ is shown to alleviate blending concerns for He_I IRT.
