Best-fit results to the UV excess and general continuum level using the slab models. The colored lines represent the individual mean epochs. The best fit components are shown for the UV excess (black, slab), photospheric template (light blue, class III), and total model (red). The data were smoothed to R ∼ 250; points below 20% the median level are masked; and a dashed line at 10⁻¹⁸ erg/s/cm²/Å is plotted at each epoch. All spectra are given in erg/s/cm²/Å units. The modeling provides a good fit to the UV excess and shows that almost all epochs have their continuum dominated by the shock-component extending to higher wavelengths. This is particularly evident in outburst epochs (2022-10-14/15).
