Optical/UV SED at MJD 58062 (close to the peak of the outburst). The colour code of the observations is the same as in Fig. 10 of the original paper. The dash-dotted blue line represents the contribution of the irradiated Be disk. The corrected contribution of X-ray heating of the companion star is plotted with a dotted pink line, the irradiated accretion disk is plotted as a dashed brown line, and the viscously heated accretion disk is plotted with a dash-dotted green line. The sum of the four components of the model is represented with a solid blackline.
