Model B. Upper panel: Observed delay from Fausnaugh et al. (2016) is represented in black. The delay calculated from the disk response function alone is shown in red, while the delay calculated from the combined response function of the disk and BLR is shown in brown. Bottom panel: Observed SED from Mehdipour et al. (2015) is shown in blue. The disk SED is represented in red, while green illustrates the disk SED combined with the emission lines. The starlight contribution is represented in black, while the warm corona is shown in orange. The final SED, incorporating contributions from the disk, star, warm corona, and emission lines, is shown in purple. The selected points used for estimating the χ² value are represented by brown squares.
