Normalized hotspot light curves obtained for an orbital radius equal to the value of the best fit. The flux is in arbitrary units. Left: hotspot radius equal to the best fit value. Inclination i varies over all grid values. (The range of these parameters are defined in Sect 5.2.3.) The closer the inclination to 90°, the higher the ratio between the two local maxima. Right: inclination fixed at its best fit value and R varies over all grid values. The smaller R, the bigger the ratio between the two subflare peaks. The time interval between the two local maxima is the same for all curves in these two figures.
