The complete ASAS magnitude time series (top panel), together with a selection of time segments. In the left panels, we plot the time series magnitudes with an overplotted sinusoid (solid curve) of P = 5.04 d rotation period. In the middle panels, we plot the periodograms with indication of the 99% confidence level (horizontal dashed line) and the power peak corresponding to the rotation period. Finally, in the right panels we plot the phased light curves using the P = 5.04 d period and the first JD of the time segment as initial epoch. Here again the solid curve is the fitting sinusoid.
