Observed (dots) and simulated (solid line) light curves in the r-Sloan (top) and i-Sloan (middle) bands, folded onto the orbital period (1.96 days) obtained from the PDM analysis. The error bar at the bottom of the plot represents the average measurement uncertainty for the data set. Bottom: The normalized V-band light curve obtained from the ASAS III catalogue folded with a period of 1.96 days.
