Fig. 1
Optical photometric lightcurve (top, red) and EWHα (bottom, blue) of LS I +61 303 plotted as a function of MJD (left) and folded with the orbital phase (right). Error bars represent 1σ uncertainties. The solid curves in the right-hand panels represent sinusoidal fits to the orbital variability, whose parameters can be found in Table 3. Two cycles are displayed for clarity.
