Models considered in this work to fit the optical/UV observations (red points) and XRT spectra (purple line) for days 58062 MJD (up) and 58094 MJD (bottom). The contribution of X-ray heating of the companion star is represented with a pink dotted line, the irradiated disk is plotted as a brown dashed line, the viscously heated disk is plotted with a green dash-dotted line. The xspec models bbodyrad and pegpowerlaw used to fit the XRT spectra are plotted with light blue dotted and navy blue dashed lines, respectively.
