Comparison of the model spectra of SN 2022xlp at different epochs. The model spectra calculated with the fitted density and Na-corrected abundance profile are shown with blue curves. In contrast, the spectra computed using exactly the adopted density and abundance profiles of the def_2021_r48_d5.0_z model are shown with red curves. Apart from the density and abundance profiles, the values of the other parameters are identical at each epoch.
