Reconstructed spectral energy distribution of the Crab nebula for the standard HAP configurations, Mono (gray lines and full circles), and Stereo (orange lines and full squares), and Event types (purple lines and stars). The full lines show the best-fit model, and the shaded areas show their statistical uncertainty ranges. The dashed black line shows the best-fit model from Aharonian et al. (2024) as a comparison. The center and bottom panels show the residual to the best-fit model of each configuration and to the model of Aharonian et al. (2024), respectively. The dark and light brown bands show the ±10% and ±20% ranges. Run-by-run corrections to observation conditions are applied to all the spectra.
