Impact of the assumed flare temperature on the cumulative FFD. Colored markers show the K2 cumulative FFD recomputed for different assumed flare temperatures, and dashed lines show power-law fits to the high-energy regime. For a fixed observed flux enhancement, a higher ﹩{T}_{{\rm{flare}}}﹩ implies a smaller inferred TESS-band flare energy, shifting the K2-based FFD to lower ETESS. In particular, adopting a solar-like white-light temperature (﹩{T}_{{\rm{flare}}}\sim 9000﹩ K) shifts the K2 FFD sufficiently that its extrapolation becomes inconsistent with the FFD from JWST observations.
