Temporal evolution of the V -band brightness (top), Hα line equivalent width (middle), and peak separation (bottom) computed with the periodic model of Haubois et al. (2012, their Fig. 7) consisting of a series of one-year disc build-up phases followed by one-year dissipation phases. Solid, dotted, and dashed lines represent inclination angles 80°, 70°, and 60°, respectively. It should be noted that the difference in sign between the V magnitude changes at 80° and 60°. The outburst begins at t = 8 yr and ends at t= 9 yr.
