Left panel: ACIS-S Chandra spectrum with BORUS model and residuals. The solid red line represents the best-fit model, the dotted line represents the reflection component, and the dashed line represents the highly absorbed power-law continuum with an exponential cutoff. The spectra are slightly rebinned for better visualization. Right panel: ACIS-S Chandra spectrum with the BORSPHERE model and residuals. The solid red line represents the best-fit model, the dotted line represents the Compton reflection component, and the dashed line indicates the absorbed cutoff power-law component.
