Out-of-transit light curve folded with the fundamental period of P₀ = 12.473490 ± 0.000067 d recovered from a twelve-component Fourier-series fit (line). Only every fourth data point is plotted. Eclipse points are removed. Orbital phase is according to the elements in Table 5. We note that periastron at the eclipse mid-time takes place at 004 and is indicated as a vertical dot-dashed line. It coincides with one of the light maxima.
